I remember Kim Clement talking about how in Acts 9, Ananias was praying and God visits him and sends him to minister to Saul of Tarsus. Now what God has done is reached out to a terrorist and converted him but Ananias doesn't know anything about Saul's conversion, he's just getting directives on where to go.
The big question is, who is Paul called to go to? I was asked this by a man known as the ‘stealth Billy Graham' along with lot of other trick questions. Another of his questions was “who is the worthy person?” and that brought us to the worthy wolf!
