So my friend Jared put his candidate for Da Man in the bible. Well he had a good pick, but my personal pick is the one, the only, *drumroll*.....PAUL!!!
That's right Paul, the greatest evangelist in history. What was he in the beginning before God got hold of him, well he was a christian killing roman. Whoa whoa whoa! a what? a christian killer!? That's right. So how oh how could God get hold of him? He spoke to him one day.
Acts 9:3-5
3 And as he (Paul then Saul) journeyed, he came near Damascus: and suddenly there shined round about him a light from heaven:
4 And he fell to the earth, and heard a voice saying unto him, Saul, Saul, why persecutest thou me?
5 And he said, Who art thou Lord? and the Lord said I am Jesus whom thou persecutest: it is hard for thee to kick against the pricks.

So in the beginning Paul, then Saul was blinded by God. That's one way to get someone's attention.
continuing on...

6 And he trembling and astonished said,, Lord, what wilt thou have me to do? And the Lord said unto him, Arise, and go into the city, and it shall be told thee what thou must do.

So Paul even in the beginning submitted to God. And the rest, as they say, is history. He went on to form the first Christian church, and he was probably the most persucted Christian in history. So there is my case for Da Man in the Bible.
