God’s revelation is not limited to the pages of Scripture. Today, R.C. Sproul presents the rationale for Christians to be involved in studying a wide variety of disciplines: All truth points back to the Lord.
Augustine did not believe that naked reason had the power in and of itself to climb up to eternal truths without the aid of God’s revelation. And he said that we are dependent upon God’s revelation for all of our understanding of truth, whether it be biblical truth, theological truth, or scientific truth. Augustine argued that we are as dependent as human beings on understanding the truth of science upon the revelation of God as the eyes are dependent upon some source of light to see anything. We have been equipped with appropriate organs, optic nerves, and the like, to be able to see things. All that we need to see is built into our human structure, but without the external manifestation of light, we won’t be able to see anything. Therefore, Augustine said that the Christian ought to learn as much as he can about as many things as he can because all truth is God’s truth.
And that God’s revelation is not limited to the pages of Scripture, because Scripture itself tells us that beyond Scripture, God reveals Himself in and through nature. I would trick my students with a question in the seminary, when I would say, “How many of you believe that biblical revelation is infallible?” And they would raise their hand. And I say, “How many of you believe that the revelation that God gives in nature is infallible?” And they wouldn’t raise their hand. I’d say: “Wait a minute, this is God’s revelation. How could His revelation be fallible?” It’s not fallible when it comes through the medium of Scripture. It’s not fallible if it comes to the medium of nature. We’re the ones that are fallible, not God.
