John Piper - In all of knowable reality, God is unique. He is...

In all of knowable reality, God is unique. He is knowable not like the multiplication table or the table of elements; he alone is knowable as the one totally in control of being known. He is not at the disposal of the human mind. He is known when he wills to be known. Yet he is known in and through created reality, which is known naturally. Therefore the glory of God is exalted most not when we know God apart from observation and reading and study, but when we know God as a result of his free and gracious self-revelation in and through our earnest observation of and meditation on his work and Word in history.
