Jesus is the most important person in the history of the world. He is the one who founded the Christian religion.
The Bible is about Jesus (Luke 24:27, 44, John 5:39, Heb. 10:7). The prophets prophesied about Him (Acts 10:43). The Father bore witness of Him (John 5:37, 8:18). The Holy Spirit bore witness of Him (John 15:26). The works Jesus did bore witness of Him (John 5:36, 10:25). The multitudes bore witness of Him (John 12:17). And, Jesus bore witness of Himself (John 14:6, 18:6).
Jesus is God in flesh (John 1:1, 14). He is fully God and fully man (Col. 2:9), thus, He has two natures: God and man. He is not half God and half man. He is 100% God and 100% man. He never lost His divinity. He existed in the form of God. When He became a man, He added human nature to Himself (Phil. 2:5-11). Therefore, there is a union in one person of a complete, fully human nature and a complete, fully divine nature. Right now in Heaven, there is a man, Jesus, who is Mediator between us and God the Father (1 Tim. 2:5). Jesus is our advocate with the Father (1 John 2:1). He is our Savior (Titus 2:13). He is our Lord (Rom. 10:9-10). He is not, as some cults teach, an angel who became a man (Jehovah's Witnesses) or the brother of the devil (Mormonism). He is wholly God and wholly man, the Creator and the Redeemer. He is Jesus.
