I was watching a football game and someone said Isaiah 7 so clearly. I forgot about it and then it came back into my mind again to look it up. So here is what I got from it. Isaiah 7 is clearly pointing to the virgin birth of the Lord Jesus as the fulfillment of the passage. The Lord Jesus Christ is the sinless Immanuel and God manifest in human flesh. God over and over again reminds us who Jesus is and Christmas in a Christians heart knows Jesus is the reason for the season. Celebrate with a Joyful Heart, He's coming back again to receive us into His Kingdom.
