Jesus is the Son of God and He is God the Son. He is one of the persons of the eternal Trinity described for us in the Bible. Jesus is in every respect the full essence of Yahweh (Jehovah), as are the Father and the Spirit.
Hebrews 1:2-3, Colossian 1:16-20 and 1st Corinthians 15:20-23 state:
In the first chapter of the Gospel of John (John 1:1-2,14), Jesus is described as the “logos” or “word” of God, who is God and was with God from all eternity. The word logos means mind or reason. And, so, John started off his Gospel saying that Jesus was always God and was always with God the Father but became human to show us what the mind, reason and purposes of God the Father are truly like.

Those all mean the same thing, that Jesus is the “one like a son of man” from Daniel chapter 7 that rules from David’s throne forever (Psalm 2 & 2nd Samuel 7:16-17).
In scripture, Jesus is also called “the Lamb of God” who takes away the sin of the world (John 1:29) and the “Lion of Judah” (Judah is the Hebrew tribe into which Jesus was born) who conquers all earthly rulers set up against God at the end of time (Revelation 5:5).
In addition to dying on the cross, the Bible has accounts from multiple witnesses that Jesus rose from the dead (1st Corinthians 15:3-8)
In a very real sense, the entire Bible points directly to Jesus and His divine nature and eternal reign. And, of course, Jesus is also well-known for being the Savior of humankind, paying for our sins on the cross. In showing His power and control over history, God told His prophets hundreds (sometimes even thousands) of years before the events occurred that Jesus would:
