Jesus Christ is both God and man.
The New Testament nowhere explicitly calls Jesus Immanuel, which means God with us. However, Jesus is the fulfillment of the Old Testament prophecy. The person of Jesus is indeed God with us. Jesus came to be with us by virgin conception. The New Testament does describe the God-man in Philippians 2:5-8 and other passages.
And the Word became flesh and dwelt among us, and we beheld His glory, the glory as of the only begotten of the Father, full of grace and truth. Jn 1:14
Jesus said to them, Most assuredly, I say to you, before Abraham was, I AM. Jn 8:58
I and My Father are one. Then the Jews took up stones again to stone Him. Jn 10:30,31
Jesus said to him, Have I been with you so long, and yet you have not known Me, Philip? He who has seen Me has seen the Father; so how can you say, Show us the Father Jn 14:9
Christ came, who is over all, the eternally blessed God. Amen. Ro 9:5
He is the image of the invisible God, the firstborn over all creation. For by Him all things were created that are in heaven and that are on earth, visible and invisible, whether thrones or dominions or principalities or powers. All things were created through Him and for Him. And He is before all things, and in Him all things consist. And He is the head of the body, the church, who is the beginning, the firstborn from the dead, that in all things He may have the preeminence. For it pleased the Father that in Him all the fullness should dwell Col 1:15-19
For in Him dwells all the fullness of the Godhead bodily Col 2:9
And without controversy great is the mystery of godliness: God was manifested in the flesh, Justified in the Spirit, Seen by angels, Preached among the Gentiles, Believed on in the world, Received up in glory. 1 Ti 3:16
