The author considers an approach to a biblical defense of the faith (apologetic). He takes a look at Romans 1:18ff., with a view to finding out what the purpose of general revelation is in a Christian apologetic and what the natural man knows of God.

Ramm's thesis in this essay is that the fundamental theistic belief of the Bible is laid in the Old Testament, and whoever wishes to formulate a biblical theism must start there. The basis for a Christian apologetic must be found in the Old Testament.
