Some idiots praise Abraham for being willing to sacrifice his son because some voice in his head told him to!
Again the deliberate misrepresentation of the actual facts...
God already knew Abraham was faithful and loved him for who he was and NOT what he had given him or promised him...
However, so future generation would know and understand the requirement of that love he gave them an example. One example for those of faith would understand that Abraham knew God could give him back his son from the dead and would be faithful to his promises even if he was doing something that would not seem so.
Abraham did not hold back his son. However God DID NOT allow him to sacrifice his son and provided as he promised.
True faith: Abraham believed God could do what he said even when killing his son would have rendered that impossible to all intents and purposes...
Loyal God: Always providing a way out and assuring us he has our best interests at heart no matter how unlikely and dark the way starts to appear...
Abraham never sacrificed his SON and God never let him sacrifice his son.
Expectant FAITH and fulfilled promises and loyalty from God.
