Finally, my brothers, rejoice in the Lord. To write the same things to you is no trouble to me and is safe for you. Look out for the dogs, look out for the evildoers, look out for those who mutilate the flesh. For we are the circumcision, who worship by the Spirit of God and glory in Christ Jesus and put no confidence in the flesh— though I myself have reason for confidence in the flesh also. If anyone else thinks he has reason for confidence in the flesh, I have more: circumcised on the eighth day, of the people of Israel, of the tribe of Benjamin, a Hebrew of Hebrews; as to the law, a Pharisee; as to zeal, a persecutor of the church; as to righteousness under the law, blameless. But whatever gain I had, I counted as loss for the sake of Christ. Indeed, I count everything as loss because of the surpassing worth of knowing Christ Jesus my Lord. For his sake I have suffered the loss of all things and count them as rubbish, in order that I may gain Christ and be found in him, not having a righteousness of my own that comes from the law, but that which comes through faith in Christ, the righteousness from God that depends on faith— that I may know him and the power of his resurrection, and may share his sufferings, becoming like him in his death, that by any means possible I may attain the resurrection from the dead. Not that I have already obtained this or am already perfect, but I press on to make it my own, because Christ Jesus has made me his own. Brothers, I do not consider that I have made it my own. But one thing I do: forgetting what lies behind and straining forward to what lies ahead, I press on toward the goal for the prize of the upward call of God in Christ Jesus. Let those of us who are mature think this way, and if in anything you think otherwise, God will reveal that also to you. Only let us hold true to what we have attained. Brothers, join in imitating me, and keep your eyes on those who walk according to the example you have in us. For many, of whom I have often told you and now tell you even with tears, walk as enemies of the cross of Christ. Their end is destruction, their god is their belly, and they glory in their shame, with minds set on earthly things. But our citizenship is in heaven, and from it we await a Savior, the Lord Jesus Christ, who will transform our lowly body to be like his glorious body, by the power that enables him even to subject all things to himself.

Hebrews 1:1-4, 14 ESV

Long ago, at many times and in many ways, God spoke to our fathers by the prophets, but in these last days he has spoken to us by his Son, whom he appointed the heir of all things, through whom also he created the world. He is the radiance of the glory of God and the exact imprint of his nature, and he upholds the universe by the word of his power. After making purification for sins, he sat down at the right hand of the Majesty on high, having become as much superior to angels as the name he has inherited is more excellent than theirs. Are they not all ministering spirits sent out to serve for the sake of those who are to inherit salvation?

Hebrews 2:1-11, 14-18 ESV

Therefore we must pay much closer attention to what we have heard, lest we drift away from it. For since the message declared by angels proved to be reliable, and every transgression or disobedience received a just retribution, how shall we escape if we neglect such a great salvation? It was declared at first by the Lord, and it was attested to us by those who heard, while God also bore witness by signs and wonders and various miracles and by gifts of the Holy Spirit distributed according to his will. Now it was not to angels that God subjected the world to come, of which we are speaking. It has been testified somewhere,

“What is man, that you are mindful of him,

or the son of man, that you care for him?

You made him for a little while lower than the angels;

you have crowned him with glory and honor,

putting everything in subjection under his feet.”

Now in putting everything in subjection to him, he left nothing outside his control. At present, we do not yet see everything in subjection to him.
But we see him who for a little while was made lower than the angels, namely Jesus, crowned with glory and honor because of the suffering of death, so that by the grace of God he might taste death for everyone. For it was fitting that he, for whom and by whom all things exist, in bringing many sons to glory, should make the founder of their salvation perfect through suffering. For he who sanctifies and those who are sanctified all have one source. That is why he is not ashamed to call them brothers, Since therefore the children share in flesh and blood, he himself likewise partook of the same things, that through death he might destroy the one who has the power of death, that is, the devil, and deliver all those who through fear of death were subject to lifelong slavery. For surely it is not angels that he helps, but he helps the offspring of Abraham. Therefore he had to be made like his brothers in every respect, so that he might become a merciful and faithful high priest in the service of God, to make propitiation for the sins of the people. For because he himself has suffered when tempted, he is able to help those who are being tempted.

Hebrews 3:6-19 ESV

but Christ is faithful over God’s house as a son. And we are his house if indeed we hold fast our confidence and our boasting in our hope. Therefore, as the Holy Spirit says,

“Today, if you hear his voice,

do not harden your hearts as in the rebellion,

on the day of testing in the wilderness,

where your fathers put me to the test

and saw my works for forty years.

Therefore I was provoked with that generation,

and said, ‘They always go astray in their heart;

they have not known my ways.’

As I swore in my wrath,

‘They shall not enter my rest.'”
Take care, brothers, lest there be in any of you an evil, unbelieving heart, leading you to fall away from the living God. But exhort one another every day, as long as it is called “today,” that none of you may be hardened by the deceitfulness of sin. For we have come to share in Christ, if indeed we hold our original confidence firm to the end. As it is said,

“Today, if you hear his voice,

do not harden your hearts as in the rebellion.”
For who were those who heard and yet rebelled? Was it not all those who left Egypt led by Moses? And with whom was he provoked for forty years? Was it not with those who sinned, whose bodies fell in the wilderness? And to whom did he swear that they would not enter his rest, but to those who were disobedient? So we see that they were unable to enter because of unbelief.

Hebrews 4:1-3, 6, 10-16 ESV

Therefore, while the promise of entering his rest still stands, let us fear lest any of you should seem to have failed to reach it. For good news came to us just as to them, but the message they heard did not benefit them, because they were not united by faith with those who listened. For we who have believed enter that rest, as he has said,

“As I swore in my wrath,

‘They shall not enter my rest,'”

although his works were finished from the foundation of the world.
Since therefore it remains for some to enter it, and those who formerly received the good news failed to enter because of disobedience, for whoever has entered God’s rest has also rested from his works as God did from his. Let us therefore strive to enter that rest, so that no one may fall by the same sort of disobedience. For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and discerning the thoughts and intentions of the heart. And no creature is hidden from his sight, but all are naked and exposed to the eyes of him to whom we must give account. Since then we have a great high priest who has passed through the heavens, Jesus, the Son of God, let us hold fast our confession. For we do not have a high priest who is unable to sympathize with our weaknesses, but one who in every respect has been tempted as we are, yet without sin. Let us then with confidence draw near to the throne of grace, that we may receive mercy and find grace to help in time of need.

Hebrews 5:8-9, 11-14 ESV

Although he was a son, he learned obedience through what he suffered. And being made perfect, he became the source of eternal salvation to all who obey him, About this we have much to say, and it is hard to explain, since you have become dull of hearing. For though by this time you ought to be teachers, you need someone to teach you again the basic principles of the oracles of God. You need milk, not solid food, for everyone who lives on milk is unskilled in the word of righteousness, since he is a child. But solid food is for the mature, for those who have their powers of discernment trained by constant practice to distinguish good from evil.

Hebrews 6

Hebrews 12:1-7, 9-13, 15-29 ESV

Therefore, since we are surrounded by so great a cloud of witnesses, let us also lay aside every weight, and sin which clings so closely, and let us run with endurance the race that is set before us, looking to Jesus, the founder and perfecter of our faith, who for the joy that was set before him endured the cross, despising the shame, and is seated at the right hand of the throne of God. Consider him who endured from sinners such hostility against himself, so that you may not grow weary or fainthearted. In your struggle against sin you have not yet resisted to the point of shedding your blood. And have you forgotten the exhortation that addresses you as sons?

“My son, do not regard lightly the discipline of the Lord,

nor be weary when reproved by him.

For the Lord disciplines the one he loves,

and chastises every son whom he receives.”
It is for discipline that you have to endure. God is treating you as sons. For what son is there whom his father does not discipline? Besides this, we have had earthly fathers who disciplined us and we respected them. Shall we not much more be subject to the Father of spirits and live? For they disciplined us for a short time as it seemed best to them, but he disciplines us for our good, that we may share his holiness. For the moment all discipline seems painful rather than pleasant, but later it yields the peaceful fruit of righteousness to those who have been trained by it. Therefore lift your drooping hands and strengthen your weak knees, and make straight paths for your feet, so that what is lame may not be put out of joint but rather be healed. See to it that no one fails to obtain the grace of God; that no “root of bitterness” springs up and causes trouble, and by it many become defiled; that no one is sexually immoral or unholy like Esau, who sold his birthright for a single meal. For you know that afterward, when he desired to inherit the blessing, he was rejected, for he found no chance to repent, though he sought it with tears. For you have not come to what may be touched, a blazing fire and darkness and gloom and a tempest and the sound of a trumpet and a voice whose words made the hearers beg that no further messages be spoken to them. For they could not endure the order that was given, “If even a beast touches the mountain, it shall be stoned.” Indeed, so terrifying was the sight that Moses said, “I tremble with fear.” But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to innumerable angels in festal gathering, and to the assembly of the firstborn who are enrolled in heaven, and to God, the judge of all, and to the spirits of the righteous made perfect, and to Jesus, the mediator of a new covenant, and to the sprinkled blood that speaks a better word than the blood of Abel. See that you do not refuse him who is speaking. For if they did not escape when they refused him who warned them on earth, much less will we escape if we reject him who warns from heaven. At that time his voice shook the earth, but now he has promised, “Yet once more I will shake not only the earth but also the heavens.” This phrase, “Yet once more,” indicates the removal of things that are shaken—that is, things that have been made—in order that the things that cannot be shaken may remain. Therefore let us be grateful for receiving a kingdom that cannot be shaken, and thus let us offer to God acceptable worship, with reverence and awe, for our God is a consuming fire.

2 Thessalonians 1:1-12 NKJV

Paul, Silvanus, and Timothy, Paul, Silvanus, and Timothy, To the church of the Thessalonians in God our Father and the Lord Jesus Christ: Grace to you and peace from God our Father and the Lord Jesus Christ. We are bound to thank God always for you, brethren, as it is fitting, because your faith grows exceedingly, and the love of every one of you all abounds toward each other, so that we ourselves boast of you among the churches of God for your patience and faith in all your persecutions and tribulations that you endure, which is manifest evidence of the righteous judgment of God, that you may be counted worthy of the kingdom of God, for which you also suffer; since  it is  a righteous thing with God to repay with tribulation those who trouble you, and to  give  you who are troubled rest with us when the Lord Jesus is revealed from heaven with His mighty angels, in flaming fire taking vengeance on those who do not know God, and on those who do not obey the gospel of our Lord Jesus Christ. These shall be punished with everlasting destruction from the presence of the Lord and from the glory of His power, when He comes, in that Day, to be glorified in His saints and to be admired among all those who believe, because our testimony among you was believed. Therefore we also pray always for you that our God would count you worthy of  this  calling, and fulfill all the good pleasure of  His  goodness and the work of faith with power, that the name of our Lord Jesus Christ may be glorified in you, and you in Him, according to the grace of our God and the Lord Jesus Christ.

2 Thessalonians 2:1-17 NKJV

Now, brethren, concerning the coming of our Lord Jesus Christ and our gathering together to Him, we ask you, not to be soon shaken in mind or troubled, either by spirit or by word or by letter, as if from us, as though the day of Christ had come. Let no one deceive you by any means; for  that Day will not come  unless the falling away comes first, and the man of sin is revealed, the son of perdition, who opposes and exalts himself above all that is called God or that is worshiped, so that he sits as God in the temple of God, showing himself that he is God. Do you not remember that when I was still with you I told you these things? And now you know what is restraining, that he may be revealed in his own time. For the mystery of lawlessness is already at work; only He who now restrains  will do so  until He is taken out of the way. And then the lawless one will be revealed, whom the Lord will consume with the breath of His mouth and destroy with the brightness of His coming. The coming of the  lawless one  is according to the working of Satan, with all power, signs, and lying wonders, and with all unrighteous deception among those who perish, because they did not receive the love of the truth, that they might be saved. And for this reason God will send them strong delusion, that they should believe the lie, that they all may be condemned who did not believe the truth but had pleasure in unrighteousness. But we are bound to give thanks to God always for you, brethren beloved by the Lord, because God from the beginning chose you for salvation through sanctification by the Spirit and belief in the truth, to which He called you by our gospel, for the obtaining of the glory of our Lord Jesus Christ. Therefore, brethren, stand fast and hold the traditions which you were taught, whether by word or our epistle. Now may our Lord Jesus Christ Himself, and our God and Father, who has loved us and given  us  everlasting consolation and good hope by grace, comfort your hearts and establish you in every good word and work.
1 Timothy 1:1-20 NKJV

Paul, an apostle of Jesus Christ, by the commandment of God our Savior and the Lord Jesus Christ, our hope, Paul, an apostle of Jesus Christ, by the commandment of God our Savior and the Lord Jesus Christ, our hope, To Timothy, a true son in the faith: Grace, mercy,  and  peace from God our Father and Jesus Christ our Lord. As I urged you when I went into Macedoniaremain in Ephesus that you may charge some that they teach no other doctrine, nor give heed to fables and endless genealogies, which cause disputes rather than godly edification which is in faith. Now the purpose of the commandment is love from a pure heart,  from  a good conscience, and  from  sincere faith, from which some, having strayed, have turned aside to idle talk, desiring to be teachers of the law, understanding neither what they say nor the things which they affirm. But we know that the law  is  good if one uses it lawfully, knowing this: that the law is not made for a righteous person, but for  the  lawless and insubordinate, for  the  ungodly and for sinners, for  the  unholy and profane, for murderers of fathers and murderers of mothers, for manslayers, for fornicators, for sodomites, for kidnappers, for liars, for perjurers, and if there is any other thing that is contrary to sound doctrine, according to the glorious gospel of the blessed God which was committed to my trust. And I thank Christ Jesus our Lord who has enabled me, because He counted me faithful, putting  me  into the ministry, although I was formerly a blasphemer, a persecutor, and an insolent man; but I obtained mercy because I did  it  ignorantly in unbelief. And the grace of our Lord was exceedingly abundant, with faith and love which are in Christ Jesus. This  is  a faithful saying and worthy of all acceptance, that Christ Jesus came into the world to save sinners, of whom I am chief. However, for this reason I obtained mercy, that in me first Jesus Christ might show all longsuffering, as a pattern to those who are going to believe on Him for everlasting life. Now to the King eternal, immortal, invisible, to God who alone is wise,  be  honor and glory forever and ever. Amen. This charge I commit to you, son Timothy, according to the prophecies previously made concerning you, that by them you may wage the good warfare, having faith and a good conscience, which some having rejected, concerning the faith have suffered shipwreck, of whom are Hymenaeus and Alexander, whom I delivered to Satan that they may learn not to blaspheme.

1 Timothy 4:1-16 NKJV

Now the Spirit expressly says that in latter times some will depart from the faith, giving heed to deceiving spirits and doctrines of demons, speaking lies in hypocrisy, having their own conscience seared with a hot iron, forbidding to marry,  and commanding  to abstain from foods which God created to be received with thanksgiving by those who believe and know the truth. For every creature of God  is  good, and nothing is to be refused if it is received with thanksgiving; for it is sanctified by the word of God and prayer. If you instruct the brethren in these things, you will be a good minister of Jesus Christ, nourished in the words of faith and of the good doctrine which you have carefully followed. But reject profane and old wives fables, and exercise yourself toward godliness. For bodily exercise profits a little, but godliness is profitable for all things, having promise of the life that now is and of that which is to come. This  is  a faithful saying and worthy of all acceptance. For to this  end  we both labor and suffer reproach, because we trust in the living God, who is  the  Savior of all men, especially of those who believe. These things command and teach. Let no one despise your youth, but be an example to the believers in word, in conduct, in love, in spirit, in faith, in purity. Till I come, give attention to reading, to exhortation, to doctrine. Do not neglect the gift that is in you, which was given to you by prophecy with the laying on of the hands of the eldership. Meditate on these things; give yourself entirely to them, that your progress may be evident to all. Take heed to yourself and to the doctrine. Continue in them, for in doing this you will save both yourself and those who hear you.
