Isaiah prophesied of the coming Messiah, saying that a virgin would conceive and have a child, and his name would be called Immanuel. When Matthew quotes Isaiah he adds that Immanuel means “God with us.” That’s the true meaning of Christmas.
I recently wrote that when we could not come to God, he came to us. In Isaiah chapter nine he writes “His name shall be called Counselor, Mighty God, Everlasting Father, Prince of Peace.” If the baby in the manger is anything other than God with us, you’re not understanding the full implication of Christ’s birth. If your Jesus is not “Mighty God,” then it is a lesser than, watered-down Jesus than the one in the Bible. The angels didn’t sing to shepherds and the wise men didn’t come from afar to worship a nice guy, a guru, or some hippie that loves you just the way you are, like some kind of cosmic Mr. Rogers. The angels sang of the Creator of Heaven and Earth. The wise men bowed down to the King of Kings and Lord of Lords. Jesus set aside something of his divinity, and wrapped himself in the same flesh that you and I are made of. (Read from Colossians 1 linked below.) The same God who created water hung on the cross and said “I thirst.” Bethlehem was the first step on the long road to the cross.
Jesus is Immanuel. Of all the names he is known by in scripture, this is the time of year we are reminded that he is “God with us.” He is not a god made with human hands, built from stone or wood, whose hands do not move and ears do not hear our prayers. If the baby in the manger is anything else, then we will go through the whole Christmas thing year after year and still miss God.
