Is it a blasphemous thought to think that you hate God? Of course not! In fact, go tell God what you are thinking. He wants to hear it. Seriously. The last thing God wants is for us to shut ourselves off from Him. So if we are having blasphemous thoughts toward God, the best thing we can do is talk to God about them, so that He can show us how much He loves us, and how the God we think we hate is not actually the God He truly is.
