What the Bible says about spiritual transformation

Galatians 2:20

I have been crucified with Christ, and it is no longer I that live, but Christ lives in me. That life which I now live in the flesh, I live by faith in the Son of God, who loved me, and gave himself up for me.

Philippians 3:7-9

However, I consider those things that were gain to me as a loss for Christ. Yes most certainly, and I count all things to be a loss for the excellency of the knowledge of Christ Jesus, my Lord, for whom I suffered the loss of all things, and count them nothing but refuse, that I may gain Christ and be found in him, not having a righteousness of my own, that which is of the law, but that which is through faith in Christ, the righteousness which is from God by faith;

Colossians 3:1-10

If then you were raised together with Christ, seek the things that are above, where Christ is, seated on the right hand of God. Set your mind on the things that are above, not on the things that are on the earth. For you died, and your life is hidden with Christ in God. When Christ, our life, is revealed, then you will also be revealed with him in glory. Put to death therefore your members which are on the earth: sexual immorality, uncleanness, depraved passion, evil desire, and covetousness, which is idolatry; for which things’ sake the wrath of God comes on the children of disobedience. You also once walked in those, when you lived in them; but now you also put them all away: anger, wrath, malice, slander, and shameful speaking out of your mouth. Don’t lie to one another, seeing that you have put off the old man with his doings, and have put on the new man, who is being renewed in knowledge after the image of his Creator,

1 Peter 1:23

having been born again, not of corruptible seed, but of incorruptible, through the word of God, which lives and remains forever.

1 John 3:1-3

See how great a love the Father has given to us, that we should be called children of God! For this cause the world doesn’t know us, because it didn’t know him. Beloved, now we are children of God, and it is not yet revealed what we will be. But we know that, when he is revealed, we will be like him; for we will see him just as he is. Everyone who has this hope set on him purifies himself, even as he is pure.

2 Peter 1:3-4

seeing that his divine power has granted to us all things that pertain to life and godliness, through the knowledge of him who called us by his own glory and virtue; by which he has granted to us his precious and exceedingly great promises; that through these you may become partakers of the divine nature, having escaped from the corruption that is in the world by lust.

Ephesians 4:22-32

that you put away, as concerning your former way of life, the old man, that grows corrupt after the lusts of deceit; and that you be renewed in the spirit of your mind, and put on the new man, who in the likeness of God has been created in righteousness and holiness of truth. Therefore putting away falsehood, speak truth each one with his neighbor. For we are members of one another. Be angry, and don’t sin.” Don’t let the sun go down on your wrath, and don’t give place to the devil. Let him who stole steal no more; but rather let him labor, producing with his hands something that is good, that he may have something to give to him who has need. Let no corrupt speech proceed out of your mouth, but only what is good for building others up as the need may be, that it may give grace to those who hear. Don’t grieve the Holy Spirit of God, in whom you were sealed for the day of redemption. Let all bitterness, wrath, anger, outcry, and slander, be put away from you, with all malice. And be kind to one another, tender hearted, forgiving each other, just as God also in Christ forgave you.

Romans 6:1-14

What shall we say then? Shall we continue in sin, that grace may abound? May it never be! We who died to sin, how could we live in it any longer? Or don’t you know that all we who were baptized into Christ Jesus were baptized into his death? We were buried therefore with him through baptism into death, that just as Christ was raised from the dead through the glory of the Father, so we also might walk in newness of life. For if we have become united with him in the likeness of his death, we will also be part of his resurrection; knowing this, that our old man was crucified with him, that the body of sin might be done away with, so that we would no longer be in bondage to sin. For he who has died has been freed from sin. But if we died with Christ, we believe that we will also live with him; knowing that Christ, being raised from the dead, dies no more. Death no more has dominion over him! For the death that he died, he died to sin one time; but the life that he lives, he lives to God. Thus consider yourselves also to be dead to sin, but alive to God in Christ Jesus our Lord. Therefore don’t let sin reign in your mortal body, that you should obey it in its lusts. Also, do not present your members to sin as instruments of unrighteousness, but present yourselves to God, as alive from the dead, and your members as instruments of righteousness to God. For sin will not have dominion over you. For you are not under law, but under grace.
