Mark Galli, in the introduction to his book, writes,
The Bible is a book full of mystery and wonder. If we find we have created a doctrine of God that makes perfect sense to us, then we’re probably no longer talking about the God of the Bible. We are finite and sinful he is infinite and holy.
I tend to agreed with him, but I am cautious. First, I assume me means that we shouldn’t hold to our doctrines so tightly as to exclude the possibility of being wrong and not the idea that if a doctrine makes sense, then it is wrong… or to the negative, if a doctrine doesn’t make sense, then it is correct.
