Isaiah 7:10-11 Moreover the Lord spake again unto Ahaz, saying, ask thee a sign of the Lord thy God; ask it either in the depth, or in the height above.
Although the Jews require a sign, we’re told in 1 Corinthians 1:22, this attitude was rebuked by Christ when He said “an evil an adulterous generation seeketh after a sign.” God has given three specific signs with respect to the incarnation of Christ. There were other signs too, no doubt, such as the star of Bethlehem, but three events were specifically called signs.
First, to the unwilling king Ahaz “therefore the Lord Himself shall give you a sign. Behold a virgin shall conceive and bare a son and shall call his name Emmanuel” (Isaiah 7:14). Emmanuel means “God with us” and the sign of the virgin birth, biologically impossible without a might miracle of divine creation, assures us that the omnipotent God has entered the human family once for all. That entrance was not made in an emperor’s palace as a great conqueror, however, but in the very humblest of human circumstances and this also was a sign.
“This shall be a sign unto you,” said the leader of the angelic host, “Ye shall find the babe wrapped in swaddling clothes lying in a manger.”
There was a third sign: when the infant Jesus was brought to the temple, the aged prophet Simeon said, “Behold, this child is set for the fall and rising again of many in Israel and for a sign which shall be spoken against that the thoughts of many hearts may be revealed.”
