People who have been divorced are not unusable.

Divorce is not a four letter word. Don't treat it like it is. People who have been divorced are not unusable. They have just been through brokenness. But God restores and He still uses His people who have been through divorce, every bit as much as He uses His people who have been broken by other struggles. Stop treating divorce like the unpardonable sin and start looking at it like God does. Stop disqualifying people from working for The Lord because of it. Man should not put limits on who God will choose or who he will use. In the words of JJ Heller. "You use the least of us (in the world's eyes) to prove the strong aren't really strong at all."
