Enjoyed this C.S. Lewis quote that I saw on Dr. Winn's blog so much that I just had to nick it.
“Everyone has warned me not to tell you what I am going to tell you…They all say “the ordinary reader does not want Theology; give him plain practical religion.” I have rejected their advice. I do not think the ordinary reader is such a fool. Theology means “the science of God,” and I think any man who wants to think about God at all would like to have the clearest and most accurate ideas about Him which are available. You are not children: why should you be treated like children?
“Theology is practical. Everyone reads, everyone hears things discussed. Consequently, if you do not listen to Theology, that will not mean that you have no ideas about God. It will mean that you have a lot of wrong ones—bad, muddled, out-of-date ideas. For a great many of the ideas about God which are trotted out as novelties today, are simply the ones which real Theologians tried centuries ago and rejected. To believe in the popular religion of modern England (or America) is retrogression—like believing the earth is flat” Mere Christianity, 135-136).
I often hear Christians question the validity of theology, 'but what's the point?, what's the application of that?' as if something that does not appear to have an immediate practical application is not worth knowing. Obviously there can be a danger of theologians sitting in their ivory towers inventing irrelevent problems for themselves to solve, but this is no excuse for not doing theology. I think it's Dallas Willard who says that one of the key requirements of leaders in the church is profundity or depth of insight. This can only come from serious thought on who God is and what he's called us to do.
I believe that the best theology should lead to worship - doxology, like when Paul says 'Oh the depth of the riches of the wisdom and knowledge of God! How unsearchable his judgements, and his paths beyond tracing out! Who has known the mind of the Lord?..... For from him and through him and to him are all things. To him be the glory for ever! Amen'
