"God told Joshua to kill every man, woman, and child, and He killed masses of people in Revelation. If that’s your ‘God of love,’ I want nothing to do with Him!"
God didn’t confine His wrath to the Canaanites, or to those mentioned in Revelation. He proclaimed the death sentence upon the whole of humanity. We will all die because we have broken God’s Law. Every one of us is waiting on death row. Instead of standing in moral judgment over Almighty God, we need to judge ourselves according to the Law of God. We will find that we have a multitude of sins and therefore are deserving of punishment. Yet God, out of love, paid the penalty for our sin so we would not have to.
