“I am not knowing a man.” Mary believed from the Old Testament text that the Messiah would be a man who was born of a woman, and now the angel said that woman would be her. Since the virgin birth was not set forth clearly in the Old Testament (see commentary on Isa. 7:14), Mary assumed that she would have to be married and having sex with a man in order to conceive the Messiah, thus her statement, “I am not knowing [sexually] a man.” As it turned out, the angel revealed that God would contribute the sperm (via creation) that impregnated Mary. Although many Christians believe that Jesus Christ was “incarnated” into the flesh, in other words, placed in Mary as a complete baby at some form of development, the Bible never says that and that is not what happened. The Bible makes the case that Mary was the true mother of Jesus Christ, not just a surrogate mother for God. Jesus could not have been a true descendant of David if there were no actual genetic link to the line of David. Furthermore, what would be the point of the genealogy in Matthew? The link between Mary and Jesus in Matthew 1:16 would not be a genetic link at all. If God simply had Mary “carry” Jesus, then his only genealogy is 100% from God, not at all from David.
