Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.
โ Romans 6:6
What changes in the new birth? Let's first note that the new birth only happens when one places their faith in the atoning work of Jesus Christ on the cross, including His resurrection. That alone is the power of God to save those who believe (Romans 1:16), since Christ made the only acceptable payment for sin (the wages of sin is death).
It's the identity of the believer that has changed. The believer goes from being a sinner in God's eyes to being righteous in God's eyes (Romans 5:8). The way we choose to live our lives after being saved does not change this fact, since the flesh does not change in the new birth (John 6:63). Jesus said, "unless you believe that I AM, you will die in your sins" (John 8:24).
What all can an unsaved person do please God? "So then they that are in the flesh cannot please God" (Romans 8:8).
Some people say this means the unsaved can't hear the gospel and believe without God causing them to do so, but that just isn't true since God does not take pleasure in the death of the ungodly (Ezekiel 33:11), and is not willing that any should perish, but that all would come to a change of mind from unbelief to faith in Christ (Hebrews 6:1, 2 Peter 3:9).
At the moment of the new birth, the believer is now sanctified (made holy, set apart) once and for all (Hebrews 10:10,14), but this is the spirit of the person and not the flesh (Romans 8:9, Philippians 3:3). The believer is now spiritually alive, and this is completely and 100% apart from his works (Romans 4:1-6). This is called the righteousness of faith (Romans 4:11,13, 9:30, 10:6). Nothing else is counted for righteousness (Romans 3:22-29).
The old identity (the flesh) has died and our life is now hidden with Christ in God (Colossians 3:3). Paul wrote, "I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by faith in the Son of God, who loved me and gave Himself for me" (Galatians 2:20).
When he said "the life I now live 'in the flesh'" he doesn't mean he is still in the flesh as in he is still in his sins. This means we have eternal life by faith (Habakkuk 2:4, Matthew 9:22,29, 15:28, Mark 5:34, 10:52, Luke 7:50, 8:48, 17:19, 18:42, John 1:7, 2:23, 3:15-16,18,36, 4:10,14, 5:24,38,40,44, 6:29,35,37,39-40,47,53-54,58, 8:24,11:25-26,20:31, Romans 1:16-17, 2:4, 3:21-28, 4:3,5-6,9,11,13,16, 21-22...).
Once someone is born again, he is no longer identified as flesh and blood (John 3:6), and it is flesh and blood that cannot inherit the kingdom of God (1 Corinthians 15:50).
But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us.
โ Romans 5:8
That is the purpose of the above passage, showing that we are now saints (holy) in Christ, and can never go back to being in the flesh since we are sealed with the Holy Spirit until the day of physical redemption (Ephesians 1:13-14, 4:30, 2 Cor 1:22).
The one who is born again is the born again spirit and this part of him does not and cannot sin, because we have to be without sin to enter into Heaven (Psalm 5:4, Revelation 21:27).
