“What were we made for? To know God. What aim should we set for ourselves in life? To know God. What is ‘eternal life’ that Jesus gives? Knowledge of God. ‘This is eternal life ; that they may know you, the only true God, and Jesus Christ, whom you have sent’ (John 17:3)” (J.I. Packer, Knowing God [InterVarsity Press: Downers Grove, IL, 1973]).
