How John Mark Became Helpful

He was a deserter; a failure. And the cause of a sharp disagreement between two Christian ministers, one of them his uncle. So sharp in fact that they no longer worked together.

Later on, the one who had objected to John Mark's continued presence on the team speaks of him in very warm terms; he has proved himself to be a valuable colleague in gospel work.

So how did the change come about? How was this fallible young man recovered? Who mentored him into being a faithful gospel servant?

Barnabas took Mark and sailed for Cyprus. (Acts 15:39)

The one who didn't give up on him, presumably.
