This testimony is from a young man who was caught up in all sorts of evil, self destructive ways. He had heard about Jesus, but until being locked up in jail, he never thought he needed Him. Praise Jesus for his transformation to an "all in", kingdom worker!
Ephesians 4:22-24 ESV To put off your old self, which belongs to your former manner of life and is corrupt through deceitful desires, and to be renewed in the spirit of your minds, and to put on the new self, created after the likeness of God in true righteousness and holiness.
Galatians 2:20 ESV 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.
