In her book on Christian Doctrine, author Beth Felker Jones discusses different kinds of revelation--the way God makes Himself know or interacts with mankind. Special revelation is defined as God's revelation in/through Israel's history, Jesus' incarnation, as well as through Scripture. General or natural revelation is God self-disclosing in the human conscience, as well as through His creation. (Which arguably human conscience would fall under.) Certainly both do have some elements of validity-- or truth if you will--to them. Simply put, general revelation is useful and even important for us (humans) to be able to know some things about God, His character and who He is. He also reveals Himself to us through the Scriptures, as well as the incarnation of Jesus, and the fulfillment of the prophecies that Jesus is; as well as the history of the nation of Israel. This is what is referred to as Special revelation.
I agree that there are certainly aspects of truth to both models of revelation. However, as most people acknowledge, our sinful nature, our very humanness that was not a part of God's original plan, taints our ability to understand even our relationship with Him. I tend to agree with the “Ongoing Continuity Between General and Special Revelation.” concept, which is at its core a combination of the two. This represents the idea that general revelation is indeed useful for forming a knowledge of some aspects, but that for a fuller knowledge of God, special revelation is required. The two go hand-in-hand, in essence. This idea of continuity likely best represents where I would find myself in this discussion. I feel that we certainly are blessed with the ability to comprehend God at a basic level through our consience, and creation, but that the Scriptures are ultimately a further gift from God in our revelatory journey.
