You can cash in on your talent
You can cash in on your good looks
You can cash in on your hard work
You can cash in on your good luck
You can even cash in on all four
And still be
Talented, good looking, hard-working, and/or lucky
But if you cash in on your moral superiority
You are no longer morally superior
God set it up this way
Because He’s notoriously cash poor–
God’s lack of liquidity is so widely known
He’s universally considered to be
Solid as a rock
