"Behold, a virgin shall be with child, and shall bring forth a son, and they shall call his name Immanuel, which being interpreted is, God with us" (Matthew 1:21). Jesus Christ is the virgin born Son of God. He is the God-Man, fully God and fully Man. Jesus is Immanuel, as the full revelation of God with us.
Jesus is God with us in "the brightness of his glory, and the express image of his person" (Hebrews 1:3). He is God the Son revealing God the Father. "The express image" means Jesus is the exact likeness of the Father in all his attributes. What is God like? Look to Jesus and find the perfect answer.
Jesus is God with us in grace and truth. "We beheld His glory, the glory of the only begotten of the Father, full of grace and truth" (John 1:14). The glory of God is revealed fully in Jesus Christ. Through Jesus, God revealed his manifest presence to us.
Jesus is God with us now through the Holy Spirit. Jesus says to us, "I am with you always, even to the end of the world" (Matthew 28:20). He makes his presence known to us through faith, hope, and love (1 Corinthians 13:13). We are enabled to know God by faith in Christ. We have a living hope in God through Christ. The love of God in Christ fills our hearts. God's full revelation is in Jesus our Immanuel.
