(2 Cor. 5:17 - Therefore, if anyone is in Christ, the new creation has come: The old has gone, the new is here!!!)
A guy last night who we were ministering to looked at me and said, you have never been homeless. What an opportunity for a testimony of what Jesus can do in a persons life. 
One of my ministry tools is a written out testimony with my old, on drugs pic, and the pic with the light and Spirit of Jesus in me.
He took the pamphlet and could not believe the old and the new. 
All glory goes to God on that one. 
(Luke 8:39 - Return to your home, and declare how much God has done for you.” And he went away, proclaiming throughout the whole city how much Jesus had done for him).
