" His Son and his Book and his world are the revelation of his glory. He has made the knowledge of himself possible. The function of mystery in the awakening of God-glorifying joy is like the unexplored mountain ranges you can barely see from the magnificent cliffs where you worship. You have seen much--if only a fraction. You have climbed. You know these mountains. God has made himself known in the mountain ranges of the Bible in such a way that all the discoveries of eternity will be the revelation of the God you already know truly in Jesus Christ. Therefore, the joy you have in what you know of God is intensified by the expectation that there is so much more to see. The mystery of what you don't know gets its God-glorifying power from what you do know. God "
