Consider these limitations:
David's armour didn't fit.
John Mark was rejected by Paul.
Timothy had ulcers.
Amos' only training was in the school of fig-tree pruning.
Jacob was a liar.
David had an affair.
Solomon was too rich.
Abraham was too old.
David was too young.
Peter was afraid of death.
Lazarus was dead.
John was self-righteous.
Naomi was a widow.
Paul was a murderer.
So was Moses.
Jonah ran from God.
Miriam was a gossip.
Gideon and Thomas both doubted.
Jeremiah was a bullfrog;
Just kidding -- he was depressed and suicidal.
Elijah was burned out.
Martha was a worry-wart.
Mary may have been lazy.
Samson had long hair.
Noah got drunk, and that's not all.
Did I mention that Moses had a short fuse?
But God doesn't require any job interview.
He doesn't hire and fire like most bosses,
because He's more our Dad than our Boss.
He doesn't look at financial gain or loss.
He's not prejudiced or partial, not judging, grudging,
sassy, or brassy, not deaf to our cry, not blind to our need.
He says come, let us reason together.
Accept His invitation and Experience Transformation.
