Doc Snow took the thoughts right outta my head, from a human point of view. From a God-downward point of view, I'd say that ALL Christian conversions are equivalent to being Divinely drafted into the Army of Christ, based on Jesus' statement, "You did not choose Me, but I chose you and appointed you to go and bear fruit" in John 15:16. You'll notice, too, in the Gospels, that when Jesus said to the fellows, "Come, follow Me" there was no negotiation, simply obedience.
Granted, this is my redneckish Calvinist point of view that has had libraries of contrary literature written to refute it down through the centuries, but I find it rather comforting...but then, I would! Enjoy your day!!
