Dramatic transformation in my life is not only expected, but possible because my very nature has been changed.
My salvation brought with it not just a clean record before God, but a changed nature. The self-willed spirit I formerly possessed has been regenerated by the Holy Spirit, and His agenda is life transformation.
2 Corinthians 5:17 Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come. Galatians 2:20 I have been crucified with Christ. It is no longer I who live, but Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me. Romans 6:6-7 We know that our old self was crucified with him in order that the body of sin might be brought to nothing, so that we would no longer be enslaved to sin. For one who has died has been set free from sin.
