James 1:13 – Let no man say when he is tempted, I am tempted of God: for God cannot be tempted with evil, neither tempteth he any man
Genesis 4:8 – And Cain talked with Abel his brother: and it came to pass, when they were in the field, that Cain rose up against Abel his brother, and slew him.
9-And the LORD said unto Cain, Where is Abel thy brother? And he said, I know not: Am I my brother’s keeper?
10-And he said, What hast thou done? the voice of thy brother’s blood crieth unto me from the ground.
11- And now art thou cursed from the earth, which hath opened her mouth to receive thy brother’s blood from thy hand.
Genesis 22:2 – And He said: ‘Take now thy son, thine only son, whom thou lovest, even Isaac, 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.’
James 1:13, when paired with the precedent set by Cain’s punishment in Genesis 4:11, means that God did not tell Abraham to kill Isaac. Period.
It doesn’t mean that the Angel didn’t then stop it, or that God isn’t real, but Abraham was either dealing with a demon or a psychosis when told to kill his son.
