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. “This is life eternal, that they may know thee, the only true God, and Jesus Christ, whom thou hast sent” (John 17:3). What is the best thing in life, bringing more joy, delight, and contentment than anything else? Knowledge of God. “Thus saith the Lord, Let not the wise man glory in his wisdom, neither let not the mighty man glory in his might, let not the rich man glory in his riches; but let him that glorieth glory in this, that he understandeth and knoweth me” (Jeremiah 9:23). What, of all the states God ever sees man in, gives him most pleasure? Knowledge of himself. “I desire … the knowledge of God more than burnt offerings,” says God (Hosea 6:6).… Once you have become aware that the main business that you are here for is to know God, most of life’s problems fall into place of their own accord.
