Psa 138:8 The LORD will fulfill his purpose for me; your steadfast love, O LORD, endures forever. Do not forsake the work of your hands.
Ecc 3:14 I perceived that whatever God does endures forever; nothing can be added to it, nor anything taken from it. God has done it, so that people fear before him.
Isa 46:4 even to your old age I am he, and to gray hairs I will carry you. I have made, and I will bear; I will carry and will save.
Jer 32:40 I will make with them an everlasting covenant, that I will not turn away from doing good to them. And I will put the fear of me in their hearts, that they may not turn from me.
Rom 11:29 For the gifts and the calling of God are irrevocable.
Phi 1:6 And I am sure of this, that he who began a good work in you will bring it to completion at the day of Jesus Christ.
2Ti 4:18 The Lord will rescue me from every evil deed and bring me safety into his heavenly kingdom. To him be the glory forever and ever. Amen.
Of all whom he has called and brought to Christ, none will be lost
Joh 6:39-40 And this is the will of him who sent me, that I should lose nothing of all that he has given me, but raise it up on the last day. For this is the will of my Father, that everyone who looks on the Son and believes in him should have eternal life, and I will raise him up on the last day.
Joh 10:27-29 My sheep hear my voice, and I know them, and they follow me. I give them eternal life, and they will never perish, and no one will snatch them out of my hand. My Father, who has given them to me, is greater than all, and no one is able to snatch them out of the Father’s hand.
Rom 8:28-31 And we know that for those who love God all things work together for good, for those who are called according to his purpose. For those whom he foreknew he also predestined to be conformed to the image of his Son, in order that he might be the firstborn among many brothers. And those whom he predestined he also called, and those whom he called he also justified, and those whom he justified he also glorified. What then shall we say to these things? If God is for us, who can be against us?
Rom 8:35-39 Who shall separate us from the love of Christ? Shall tribulation, or distress, or persecution, or famine, or nakedness, or danger, or sword? As it is written, “For your sake we are being killed all the day long; we are regarded as sheep to be slaughtered.” No, in all these things we are more than conquerors through him who loved us. For I am sure that neither death nor life, nor angels nor rulers, nor things present nor things to come, nor powers, nor height nor depth, nor anything else in all creation, will be able to separate us from the love of God in Christ Jesus our Lord.
Heb 7:25 Consequently, he is able to save to the uttermost those who draw near to God through him, since he always lives to make intercession for them.
Heb 10:14 For by a single offering he has perfected for all time those who are being sanctified.
God’s preservation of the saints is not irrespective of their continuance in the faith
1Co 6:9-10 Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived: neither the sexually immoral, nor idolaters, nor adulterers, nor men who practice homosexuality, nor thieves, nor the greedy, nor drunkards, nor revilers, nor swindlers will
inherit the kingdom of God.
Gal 5:19-21 Now the works of the flesh are evident: sexual immorality, impurity, sensuality, idolatry, sorcery, enmity, strife, jealousy, fits of anger, rivalries, dissensions, divisions, envy, drunkenness, orgies, and things like these. I warn you, as I warned you before, that those who do such things will not inherit the kingdom of God.
Eph 5:5 For you may be sure of this, that everyone who is sexually immoral or impure, or who is covetous (that is, an idolater), has no inheritance in the kingdom of Christ and God.
Heb 3:14 For we share in Christ, if indeed we hold our original confidence firm to the end.
Heb 6:4-6 For it is impossible to restore again to repentance those who have once been enlightened, who have tasted the heavenly gift, and have shared in the Holy Spirit, and have tasted the goodness of the word of God and the powers of the age to come, if they then fall away, since they are crucifying once again the Son of God to their own harm and holding him up to contempt.
Heb 10:26-27 For if we go on sinning deliberately after receiving the knowledge of the truth, there no longer remains a sacrifice for sins, but a fearful expectation of judgment, and a fury of fire that will consume the adversaries.
Heb 12:14 Strive for peace with everyone, and for the holiness without which no one will see the Lord.
Rev 21:7-8 The one who conquers will have this heritage, and I will be his God and he will be my son. But as for the cowardly, the faithless, the detestable, as for murderers, the sexually immoral, sorcerers, idolaters, and all liars, their portion will be in the lake that burns with fire and sulfur, which is the second death.
Rev 22:14-15 Blessed are those who wash their robes, so that they may have the right to the tree of life and that they may enter the city by the gates. Outside are the dogs and sorcerers and the sexually immoral and murderers and idolaters, and everyone who loves and practices falsehood.
However, it is God who sanctifies us and causes us to persevere
Joh 15:16 You did not choose me, but I chose you and appointed you that you should go and bear fruit and that your fruit should abide, so that whatever you ask the Father in my name, he may give it to you.
1Co 1:30-31 He is the source of your life in Christ Jesus, whom God made our wisdom and our righteousness and sanctification and redemption. Therefore, as it is written, “Let the one who boasts, boast in the Lord.”
1Co 6:11 And such were some of you. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God.
1Co 12:3 Therefore I want you to understand that no one speaking in the Spirit of God ever says “Jesus is accursed!” and no one can say “Jesus is Lord” except in the Holy Spirit.
1Co 15:10 But by the grace of God I am what I am, and his grace toward me was not in vain. On the contrary, I worked harder than any of them, though it was not I, but the grace of God that is with me.
Gal 3:1-6 O foolish Galatians! Who has bewitched you? It was before your eyes that Jesus Christ was publicly portrayed as crucified. Let me ask you only this: Did you receive the Spirit by works of the law or by hearing with faith? Are you so foolish? Having begun by the Spirit, are you now being perfected by the flesh? Did you suffer so many things in vain – if indeed it was in vain? Does he who supplies the Spirit to you and works miracles among you do so by works of the law, or by hearing with faith – just as Abraham “believed God, and it was counted to him as righteousness”?
Eph 2:10 For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them.
Phi 2:12-13 Therefore, my beloved, as you have always obeyed, so now not only as in my presence but much more in my absence, work out your own salvation with fear and trembling, for it is God who works in you, both to will and to work for his good pleasure.
1Th 5:23-24 Now may the God of peace himself sanctify you completely, and may your whole spirit and soul and body be kept blameless at the coming of our Lord Jesus Christ. He who calls you is faithful; he will surely do it.
Heb 13:20-21 Now may the God of peace who brought again from the dead our Lord Jesus, the great shepherd of the sheep, by the blood of the eternal covenant, equip you with everything good that you may do his will, working in us that which is pleasing in his sight, through Jesus Christ, to whom be glory forever and ever. Amen.
1Jo 2:29 If you know that he is righteous, you may be sure that everyone who practices righteousness has been born of him.
Jud 1:24-25 Now to him who is able to keep you from stumbling and to present you blameless before the presence of his glory with great joy, to the only God, our Savior, through Jesus Christ our Lord, be glory, majesty, dominion, and authority, before all time and now and forever. Amen.
