I believe one of the greatest sins we can commit is to limit God. What does that mean? To limit God is to believe that God thinks and views reality as you do. It is to believe that you, despite being a sinful, fallen human being, have the mind of God, and therefore, your views and opinions are on a par with the Mind of God. If you believe something is wrong, then it is wrong, If you believe something is right, then it is right. If you believe something can't be done, then it can't be done. Limiting God actually breaks the First Commandment - have no other gods before me - because you are making yourself into God.
Limiting God is the exact opposite of faith. Those who limit God say this is what God thinks and this is what God does, no more and no less. Faith says God is so far beyond my comprehension that I can't begin to fathom how He thinks. Faith says I am a sinner with a twisted, distorted and microscopically small view of reality. I am like an ant crawling on the ground with an ant's view of the world and the universe. An ant believes the only way to do things is the way he does them, by crawling around on the ground. Likewise, one who limits God, i.e. a faithless person, believes his way is the only way. If something doesn't fit into his understanding, then it can't be done. End of discussion.
