Whatever our beliefs, we all believe something about God. Even if our belief is to disbelieve in the existence of any god or higher power, we still believe something about who God is and what he is like. And these ideas that really do affect every other aspect of our lives. And this has created a problem for many western Christians, who don't seem to really know the God we say we believe in—we lack a foundation in the truths we believe. We need to learn to re-ignite our relationship between the truths we confess, the way we live, and our emotional life. To not focus solely on the head or the hands, but to deal with our hearts too. 

One book that can help? Knowing God by J. I. Packer. After you read it, it might just be your next favorite book.
