PAUL wrote to the Galatians, “When the fullness of the time was come , God sent forth His Son, made of a woman, made under the law, to redeem them that were under the law, that we might receive the adoption of sons.”
The reservoir of time had to be filled by the inflowing of age after age; and when it was full to the brim, the Son of God appeared. Why the world should have remained without Him who is its one great Light for four thousand years after Adam was formed out of the dust of the earth, and why it should have taken that length of time for the Jewish Church to attain her full age, we cannot tell; but this we are plainly told, that Jesus was sent forth “when the fullness of the time was come.” Our Lord did not come before His time, nor behind His time; He was punctual to the appointed hour, and cried, to the exact moment, “Lo, I come.”
We may not curiously pry into the reasons why Christ came just when He did; but we may reverently muse on the great fact. The birth of Jesus is the grandest light of history, the sun in the heavens of all time. It is the pole star of human destiny, the hinge of chronology, the meeting place of the waters of the past and the future. Why did it happen just at that moment?
The main reason is, because it was so predicted. There were many prophecies, in the Old Testament Scriptures, which pointed, as with unerring fingers, to the place, the manner, and the time when the Shiloh would come, and the great sacrifice for sin should be offered. Jesus came at the very hour which God had determined.
