Revelation, be it in nature, within ourselves, or inscripturated in a book, is always God’s prerogative. It always comes from God, and man is designed to receive it. Man is not the one who starts with himself and discovers God in the universe, rather God discloses himself, and man ought to take immediate notice of God’s self-revelation.
Let me start with a basic definition of general revelation: General Revelation is God’s self-disclosure in nature and in the psychological aspects of man.
The Range of the Revealed
I am not saying that the physical aspects of man are not revelatory, they are, but I include those within the general heading of nature. So material nature and also our psychology are both revelatory of the Triune God, the God who reveals himself in the Scriptures. They are not revelatory of any other god for the simple reason that there is no other god who can reveal himself, and therefore the revelation that we see is the revelation that we ought to ascribe to our Creator.
Because of the connections between the human psyche and nature, the material world (what God has made) is revelational, not the other way round. This brings together the fact of divine revelation with the expectancy for divine revelation. We know that God has revealed Himself because He has told as in His Scriptures and He’s put it all around us. We expect that God reveals Himself in the world because of what He’s told us about Himself.
