Two fishermen come in from wading the waters.
Simon: Catch anything?
Andrew: Nothing. A big fat nothing. There isn’t anything out there.
Voice from the shore: Go back out, cast your nets deeper.
Simon: You know him?
Andrew: Saw him here the other day. He’s the one who fed everyone with two fish and five loaves.
Voice from the shore: In the deep water, beyond the rock.
Simon: Funny look in his eye.
Andrew: Go back out? Give it a try?
Simon: Give it a try.
And the rest is history.
Telling a fisherman to go out again is like preaching to the converted.
Good persuasion is a set of confident directions.
It will convert the despairing, empty-handed into true believers.
