To a considerable extent we can assent to and wholeheartedly affirm this doctrine of the unknowability of God. Scripture and the church emphatically assert the unsearchable majesty and sovereign highness of God. There is no knowledge of God as he is in himself. We are human and he is the Lord our God.
