"Augustus Caesar was ruling, but God was in charge, for He used Caesar's edict to move Mary and Joseph eighty miles from Nazareth to Bethlehem to fulfill His Word. Rome took a census every fourteen years for both military and tax purposes, and each Jewish male had to return to the city of his fathers to record his name, occupation, property, and family. When Mary said "Be it unto me according to Thy word" (Luke 1:38), it meant that from then on, her life would be a part of the fulfillment of divine prophecy.
God had promised that the Saviour would be a human, not an angel (Gen. 3:15; Heb. 2:16), and a Jew, not a Gentile (Gen. 12:1-3; Num. 24:17). He would be from the tribe of Judah (Gen. 49:10), and the family of David (2 Sam. 7:1-17), born of a virgin (Isa. 7:14) in Bethlehem,' the city of David (Micah 5:2).All of this occurred just as the Scriptures said, and Caesar unknowingly played an important part.
A.T. Pierson used to say, "History is His story," and President James A. Garfield called history "the unrolled scroll of prophecy." If God's Word controls our lives, then the events of history only help us fulfill the will of God. "I am watching over My word to perform it," promises the Lord (Jer. 1:12, NASB)
