And it came to pass after these things, that God did tempt Abraham, and said unto him, Abraham: and he said, Behold, here I am.
2 And he said, Take now thy son, thine only son Isaac, whom thou lovest, and get thee into the land of Moriah; and offer him there for a burnt offering upon one of the mountains which I will tell thee of.
My first response to this is how did Abraham know he wasn't being tricked by satan into killing his son?
And then when Isaac asks where the lamb is for the burnt offering, and Abraham responds by telling him God will provide, whew! what faith.
But again, it is such a serious situation to be asked to sacrifice your son, Abraham seemed to doubt God's promise of a son when he was aging and now he had Isaac and he shows no second thought in taking isaac to sacrifice him? Wouldn't it make you question your sanity if you thought God wanted you to kill your son?
