EXACTLY.
I have a friend who has quite the past, drug use, drug dealing, extortion, promiscuous, violent.
Got saved in his twenties and gloriously converted.
Now, some 40 years later, he’s involved in a very fruitful jail ministry and can relate to these people wand where they are coming from and they KNOW that he’s been where they are. It gives him great credibility with them.
He surely does work in "mysterious" ways.
