"God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets, hath in these last days spoken unto us by His Son." Hebrews 1:1. God has been speaking from the beginning. Creation itself is an expression of His thought, and all His providential government — where there are eyes to see — gives witness to His eternal power and Godhead, so that men are without excuse. In a special way, He has spoken through the prophetic ministry of His servants during the entire period covered by the Old Testament. These Old Testament Scriptures give us the record and manner of God's speaking in time past. The instruments He used were the prophets, but the Author is God. But there is a change in the Gospels — the Son Himself has come, and is speaking. "In these last days" — an expression significant of a change from His former methods of appealing to man, as well as a declaration that no further unfolding remains to be revealed — "He hath spoken unto us by His Son," or to be absolutely literal, "in a Son." This does not suggest that there are other sons, but gives the great fact of His Son standing out all alone. There is but One; no need even to designate Him in any exclusive way. The expression shows us that God's manner of communication has changed. It is not merely that we have inspired and authoritative messengers who declare unto us the will of God in many parts and in many ways — in details of biography, in historic events, in types, etc. but God Himself is present in the Son.
