An angel appeared before a woman named Mary and announced to her that she would give birth to a son. She would have called her son Jesus. Mary, being a virgin, gave birth to a child, conceived by God through his Spirit. Jesus being supernaturally conceived became man and God in one creation. God became incarnate in this child who became known by the name Jesus (Matthew 1,18-25). Jesus was a Palestinian Jew, born in a town south of Jerusalem, raised in Nazareth in a small village in Galilee. Jesus was not just any child. Jesus was the son of the living God. Not only was he the son of Mary, he was above all the Son of God. He became incarnate and was sent to us for the redemption of all humanity. So how do we handle the incarnation of God? The humanity and divinity of Jesus are union in one human body. God now lives in the flesh as Jesus of Nazareth. He is not half God and half man. He is fully divine and fully man. Jesus has two distinct natures (Divine and Human). Jesus was the word, and the word was with God and became flesh (John 1:1–14). This means that Jesus has both a human nature and a divine nature existing in one body (eis en prosopon k is ai mian hpostasin) of Jesus is the incarnation of God in man. However, due to the vague meaning of the word, it is necessary to define the nature of the incarnation. Jesus was fully God and fully man at the same time. It is necessary for Jesus to be completely God and completely man in order to truly become incarnate. God being both human and divine leaves us with daunting questions regarding Jesus' human nature and his divine nature. How did Jesus' nature operate in one body? This research paper will look at several theories that attempt to explain the two natures of Jesus' existence in one body... halfway through the paper... we were not fully human and only God was pretending to be human, then there is no triumph in its perfection. If there is no success in its perfection, then there can be no sacrifice. However, if God were man, but not fully God, then He would have no power or authority over sin. If Jesus could sin, he could not be the sacrificial lamb. And the man would have no atonement. John writes that the Word was with God and that the Word was God and that Jesus (the word) was with God in the beginning and that through him (Jesus) all things were made (John 1:1,2). Not only did John understand that Jesus was God, but Jesus himself understood it. He said: “He who has seen me has seen the Father; how can you say: 'Show us the Father'?” (John 14:9). Jesus was not saying that He is literally the Father, but that He is essentially one with the Father, who is God incarnate.
