Buy the book
If you have not read the book Knowing God, by J. I. Packer, you have missed one of the most influential books of the past 40 years. I have read it more often and given it away more frequently than any other book.
Here is a quote to whet your appetite. Take 30 seconds to read it – then go buy the book. You will never regret the purchase.
“Knowing about God is crucially important for the living of our lives. As it would be cruel to an Amazonian tribesmen 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.”
