Therefore if anyone is in Christ, he is a new creature; the old things passed away; behold, new things have come. (2 CORINTHIANS 5:17 NASB)
that, in reference to your former manner of life, you lay aside the old self, which is being corrupted in accordance with the lusts of deceit, and that you be renewed in the spirit of your mind, and put on the new self, which in the likeness of God has been created in righteousness and holiness of the truth. (EPHESIANS 4:22-24 NASB)
For if we have become united with Him in the likeness of His death, certainly we shall also be in the likeness of His resurrection, 6knowing this, that our old self was crucified with Him, in order that our body of sin might be done away with, so that we would no longer be slaves to sin; 7for he who has died is freed from sin.
8Now if we have died with Christ, we believe that we shall also live with Him, 9knowing that Christ, having been raised from the dead, is never to die again; death no longer is master over Him. 10For the death that He died, He died to sin once for all; but the life that He lives, He lives to God. 11Even so consider yourselves to be dead to sin, but alive to God in Christ Jesus. (ROMANS 6:5-11 NASB)
