Knowledge
Which method fits with a certain system of thought depends upon the idea of knowledge a system has. For the Christian system, knowledge consists in understanding the relation of any fact to God as revealed in Scripture. I know a fact truly to the extent that I understand the exact relation such a fact sustains to the plan of God. It is the plan of God that gives any fact meaning in terms of the plan of God. The whole meaning of any fact is exhausted by its position in and relation to the plan of God. This implies that every fact is related to every other fact. God’s plan is a unit. And it is this unity of the plan of God, founded as it is in the very being of God, that gives the unity that we look for between all the finite facts. If one should maintain that one fact can be fully understood without reference to all other facts, he is as much antitheistic as when he should maintain that one fact can be understood without reference to God.
