It sounds like a very fulfilling career. Always good to know people like you exist out there helping others. Sorry to hear about your friend. Glad to hear he has improved himself to become a better man.No, I don't go to the prison to work there as a guard.
I'm part of two different Christian ministries at one of the nearby prisons and I'm out there often. Then each week, I go to the local jail to share the Bible with men in there.
I do get a kick out of the reaction I get when I tell people one of my best friends is in prison with a life without parole sentence. I wouldn't have wanted to know him back when he was a heroin addict and killed someone, but after he accepted Christ as his Lord and Savior, he changed. He'll never see the outside of a prison in this lifetime, but he's chosen a different way to live out the rest of this life. So it does make a difference.
