Since our life began at a certain time in this world, we are all finite beings. It dawned on me that this is why we have trouble perceiving infinity. When scientists searched for how the universe began, they came up with the big bang theory which had a beginning. But what came before that? When I was a little kid, I wondered if I would ever run into a wall if I kept flying into the sky. If I did hit one, then what'd be on the other side? I gave up. You see, our mind is incapable of dealing with things that are infinite. Since God by definition has no beginning and no end, we with the finite mind have trouble in believing in his existence. Naturally, if you were God, infinity would be the norm. I hope I have hit on something that can help you believe in God more readily.
