I believe God exists and I believe in God. As Paul so aptly put it in Romans 1: “For his invisible attributes, that is, his eternal power and divine nature, have been clearly seen since the creation of the world, being understood through what he has made. As a result, people are without excuse.”
This whole article is worth the read but this is a good argument.
So why do skeptics, like Bertrand Russell, say there isn’t enough evidence? I submit to you that they’re looking in the wrong places. They’re looking for God to do something inside the creation — like do a miracle, appear to them, or give them a special message — when all they need to do is consider the origin and design of the universe.
This would be equivalent to me denying D. R. Horton’s existence (my home builder) because I don’t see him anywhere in my house. I’ve checked all the rooms, the garage, and even the attic, but I can’t find him. Therefore, I conclude, he must not exist.
But that’s absurd. Of course he exists! How do you suppose my house got there? And what about all the evidence for design on in the inside and outside of the house? It’s evident, based on the house itself, that D.R. Horton exists. In the same way, when we consider the origin and design of our universe, it’s evident that God exists too.
