As indicated in an earlier connection, man’s creation in God’s image involves (a) the fact that man’s ideal of knowledge should never be that of the comprehension of God, and (b) the fact that man’s knowledge is nevertheless true.

What we have now spoken of as the presuppositions of revelation are nothing more than the presuppositions of a truly Christian theistic theory of knowledge. God had in himself all knowledge from all eternity. Nothing could be added to his store of knowledge in any process of time. In accordance with his plan, or, as we may say, in accordance with his interpretation, all finite things were made. Hence, all knowledge that any finite creature of God would ever have, whether of things that pertain directly to God or of things that pertain to objects in the created universe itself would, in the last analysis, have to rest upon the revelation of God.
