No, you only believe that God exist. Belief is personal. Knowledge is demonstrable. If you can show that God exists then you can claim to know. Until you do that you only have mere belief. Your claim of knowing that God exists is no different from a Muslim's claim that they know that Allah exists or a Hindu's claim that they know that Brahma exists.Of course. If what I say does not speak to you and you doubt it that is your reality. I respect that. I have done what I said in that last part of my statement and sought God's answer, I have received His answer. I know that He exists. I also know that this answer came to me and I cannot use it to prove anything to anyone who does not wish to believe what I say. And I think wise persons would do their own inquiry, it is a sure way to find out, if one wants to actually find out and obtain real proof. Proof from God is the ONLY real proof.
