" It made no sense that Abraham could head for the mountain in Moriah still believing in God's goodness. It made no sense that even as he walked his son to the sacrificial altar, he still believed God's promise that Isaac would give him many descendants. It made no sense that he was willing to do the one thing in the world he could not do, just because God told him to. God told him to obey and to believe that he as a loving god and could be trusted. So Abraham did obey. "
