Should Christians Concern Themselves with Theology?

When presented with the question... "Should the average Christian care about Theology?" ... J.I. Packer responded with these words...

"A fair question! - but there is, I think, a convincing answer to it. The questioner clearly assumes that a study of the nature and character of God will be unpractical and irrelevant for life. In fact, however, it is the most practical project anyone can engage in. Knowing about God is crucially important for the living of our lives.

As it would be cruel to an Amazonian tribesman to fly him to London, put him down without explanation in Trafalgar Square and leave him, as one who knew nothing of English or England, to fend for himself, so we are cruel to ourselves if we try to live in this world without knowing about the God whose world it is and who runs it.

The world becomes a strange, mad, painful place, and life in it a disappointing and unpleasant business, for those who do not know about God. Disregard the study of God, and you sentence yourself to stumble and blunder through life blindfold, as it were, with no sense of direction and no understanding of what surrounds you. This way you can waste your life and lose your soul."

J.I. Packer, Knowing God, p.18-19.
