The Gospel is the power of God, and the power of God is manifest in the things that He has made; therefore the Psalmist is speaking of the Gospel, which the heavens teach. The Apostle Paul in Romans 10:15-18 shows that this is so, "How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things! But they have not all obeyed the gospel. For Isaiah says, Lord, who has believed our report? So then faith comes by hearing, and hearing by the word of God. But I say, have they not heard? Yes verily, their sound went into all the earth, and their words unto the ends of the world." The apostle is here speaking about the Gospel, which, he says, all have not obeyed. Then he declares that all have heard, and as proof that they have all heard he quotes from Psalm 19, "Their line is gone out through all the earth, and their words to the end of the world." Their words concerning what? Why, concerning the Gospel, of course. Thus we have a plain statement that the heavens do preach the Gospel. There is no man so illiterate that he cannot read the Gospel; no man so deaf or so isolated that he cannot hear a gospel sermon. This truth will be more evident as we proceed.
