God`s irony is that Paul was chosen for his mission....in spite of his past. A miracle.
It truly was! It's hard to find a stronger testimony to the power of God through the gospel of Jesus Christ than a man who was hell-bent on destroying Christians and Christianity to become one of its greatest apologists.
I suspect that this attack on Paul is more to do with the fact that he says things that are apropos to this very age we are living in. Paul pricks the conscience. It is as simple as that!
