The truth is, God told Abraham to kill a baby goat, not his kid.
But Abraham, being almost a hundred, didn’t hear God too well, so he headed up the mountain for the sacrifice.
God left a few signs along the path that said I SAID KILL A BABY GOAT, NOT YOUR KID, but Abraham was illiterate.
God tried a few signs with simple pictograms, but Abraham’s eyesight wasn’t too good, either.
Which is a good thing, because he mistook a small goat for his son.
“That’ll do,” said God.
No wonder why Moroni gave magic spectacles to John Smith.
