According to Scripture, God has created the “universe.” God has created time and space. God has created all the “facts” of science. God has created the human mind. In this human mind God has laid the laws of thought according to which it is to operate. In the facts of science God has laid the laws of being according to which they function. In other words, the impress of God’s plan is upon his whole creation.
We may characterize this whole situation by saying that the creation of God is a revelation of God. God revealed himself in nature and God also revealed himself in the mind of man. Thus it is impossible for the mind of man to function except in an atmosphere of revelation. And every thought of man when it functioned normally in this atmosphere of revelation would express the truth as laid in the creation by God. We may therefore call a Christian epistemology a revelational epistemology.
