The question is: "can we construct a theology based upon man-made conclusions of observations from God's general revelation? Today's post aims to offer some thoughts as to why this effort is not only possible, but also Biblical. Throughout the course of this post, I will also briefly introduce the reader to the most commonly used method of articulating and defending the Christian faith: "classical Christian apologetics". At the end of the post, I will give the reader links to various websites that specialize in defending and articulating the Christian faith (i.e Christian apologetics).
If anything, what God reveals of Himself in general revelation does not conflict with what He reveals specifically in the Word of God. The only conflicts we may see is in the man-made efforts to systematize either His general revelation (hence "natural theology") or to systematize His special revelation in the Bible in communicating His Word to the modern mind (the task of systematic theology).
Isaiah 41:21-26 uses the relationship between cause and effect, as well as historical argumentation to judge whether something is Divinely revealed by the true God. Jesus often used illustrations from agriculture (Matthew 13), viticulture or the practice of farming grapes (John 15) and birds (Mt 6:25-34) to illustrate spiritual truths.
As observations from general revelation and natural theology are used, we find that a reasonable basis for belief in God is shown.
Typically, those using the classical apologetic method will proceed along the following pattern:
3). Usually arguments for the reliability of scripture will be part of the overall case for the Christian worldview. If the apologist so chooses, appeal may be made to instances of fulfilled prophecy in history and the vast manuscript evidence demonstrating the credibility of the Biblical text.
More could be said, but for now, the case for God's existence in general, and the reality of God's revelation of Himself in Jesus and the Bible has been ably defended for centuries and millennia by Christians against skeptics. Long after Christianity's opponents and their systems have passed off the scene, the truth of God, the Lord Jesus Christ and the scriptures stands as a granite rock of truth.
