The importance of virgin birth of the incarnate Jesus Christ cannot be overstated. If Jesus was not born of a virgin, then Jesus was a man like you or me. He had a sin nature like you or me. If Jesus was not born of a virgin, then he could not be the Son of God. He could not be sinless. He could not be a substitutionary sacrifice. And He could not be the Savior of mankind. 

The virgin birth of Jesus is often the first truth about Jesus to be attacked. The virgin birth fulfilled prophecy, declares Jesus' purity, and reveals God's purposes.
