One of the names given to Jesus is “Immanuel” (Matthew 1:23). Literally, this means, “with us God.” In better English, we say, “God with us.” This is the great reality of Christmas: that God came down from heaven to dwell with us on earth. This all took place in the past.
Another reality of Immanuel is often missed. It’s Immanuel in the future. When believers enter heaven to dwell with God forever, it will again be “God with us.” This is what Jesus promised to those who believe in him. “I will come again and will take you to myself, that where I am you may be also” (John 14:3).
The picture of the new heaven in Revelation expresses this reality with these words. “Behold, the dwelling place of God is with man. He will dwell with them, and they will be his people, and God himself will be with them as their God” (Revelation 21:3). This is the great reality of eternity. Believers in Christ will experience “Immanuel” forever.
