Yes—I know what you mean, about knowing God exists. I think I truly believed in God, and in the existence of the soul, the day I watched my beloved grandmother pass away. I cannot exactly describe this (and I was only a teenager at the time) but I could tell the moment her soul left her body. How tragic, to not believe that we can live forever, with Christ! How amazing, that our Creator would lower Himself to become a man, so that we could know Him!
what a beautiful way to put it. Belief brings the ability to see miracles.
