A loving God won't judge . This is something I've struggled with quite a bit. I wonder about those who didn't get a clear, relevant presentation of the gospel like I did. And I think about the fact that eternal punishment is an awfully big sentence for what most people do. Some are innocent because they lack the ability to grasp their moral state.
Natural revelation gives everyone reasonable and intuitive awareness of the human condition.
Abraham did not know the full plan of God. He only knew that God was calling him, and that he should act in obedience. Because what intuition a person has gets lost and distorted in false religion. Eternal punishment for finite sins . God's desire is that all be saved.
