Therefore the Lord himself will give you a sign. Behold, the virgin shall conceive and bear a son, and shall call his name Immanuel. (Isaiah 7:14)
Now the birth of Jesus Christ took place in this way. When his mother Mary had been betrothed to Joseph, before they came together she was found to be with child from the Holy Spirit. And her husband Joseph, being a just man and unwilling to put her to shame, resolved to divorce her quietly. But as he considered these things, behold, an angel of the Lord appeared to him in a dream, saying, “Joseph, son of David, do not fear to take Mary as your wife, for that which is conceived in her is from the Holy Spirit. She will bear a son, and you shall call his name Jesus, for he will save his people from their sins.” All this took place to fulfill what the Lord had spoken by the prophet:
“Behold, the virgin shall conceive and bear a son,
and they shall call his name Immanuel”
(which means, God with us). When Joseph woke from sleep, he did as the angel of the Lord commanded him: he took his wife, but knew her not until she had given birth to a son. And he called his name Jesus.
Immanuel means God did not abandon us. He did not leave us to ourselves.
Immanuel points to that mystery of God becoming man and dwelling among us, feeling our human wants, griefs, and pains.
Immanuel points to that future consummation when in the new heavens and earth, God's dwelling place comes down to that new earth and God and man dwell together forever.
Immanuel means we can live with hope, having the forgivness of our sins, and having peace with God.
Imanuel; the proof of God's love and intent to save a lost and fallen humanity...
Immanuel! All praise and honor and glory to God and God alone!
