‘What were we made for?  To know God.  What aim should we set ourselves in life?  To know God.  What is the “eternal life” that Jesus gives?  Knowledge of God … What is the best thing in life, bringing more joy, delight, and contentment, than anything else?  Knowledge of God … What, of all the states God ever sees [us] in, gives Him most pleasure?  Knowledge of Himself.’ So writes J.I. Packer in his influential book, Knowing God)
