JESUS came down from Heaven to be born and live here to redeem us from our sins. HE is the Messiah, the redeemer! Back in the Book of Isaiah because of their sins GOD called them out to turn from their sins and return to serving HIM. As a whole they did not, just like they did when JESUS came to earth and died on a wooden cross of wood being nailed to it bleeding out HIS Holy pure blood for all of us who lived on this earth. In the Book of Isaiah chapter 7 verse 14 it was foretold a Messiah would be born. Around 700 hundred years in the future in a historical timeline I found JESUS was born as Isaiah 7:14 said.
The Scripture in Isaiah 7:14 reads: Therefore the LORD Himself shall give you a sign; Behold, a virgin shall conceive, and bear a son, and shall call HIS name Immanuel.
