the Witness of the Stars before written text

For more than two thousand five hundred years the world was without a written revelation from God. The question is, Did God leave Himself without a witness? The question is answered very positively by the written Word that He did not. In Romans 1:19 it is declared that, "that which may be known of God is manifest in them; for God hath showed it unto them. For the invisible things of Him from the creation of the world are clearly seen, being understood by the things that are made, even His eternal power and Godhead; so that they are without excuse." But how was God known? How were His "invisible things," i.e., His plans, His purposes, and His counsels, known since the creation of the world? We are told by the Holy Spirit in Romans 10:18. Having stated in v. 17 that "Faith cometh by hearing and hearing by the Word (the thing spoken, sayings) of God," He asks, "But I say, Have they not heard? Yes, verily." And we may ask, How have they heard? The answer follows--"Their sound went into all the earth and their words (their teaching, message, instruction) unto the ends of the world." What words? What instruction? Whose message? Whose teaching? There is only one answer, and that is, THE HEAVENS! This is settled by the fact that the passage is quoted from Psalm 19, [one] part of which is occupied with the Revelation of God written in the Heavens, and the part with the Revelation of God written in the Word.
