Jesus is the most important person who has ever lived since he is the savior, God in human flesh. He is not half God and half man. He is fully divine and fully man. In other words, Jesus has two distinct natures: divine and human. Jesus is the Word who was God and was with God and was made flesh, (John 1:1,14). This means that in the single person of Jesus is both a human and divine nature, God and man. The divine nature was not changed when the Word became flesh (John 1:1,14). Instead, the Word was joined with humanity (Col. 2:9). Jesus' divine nature was not altered. Also, Jesus is not merely a man who "had God within Him" nor is he a man who "manifested the God principle." He is God in flesh, second person of theTrinity."The Son is the radiance of God's glory and the exact representation of his being, sustaining all things by his powerful word,"(Heb. 1:3). Jesus' two natures are not "mixed together," (Eutychianism) nor are they combined into a new God-man nature (Monophysitism). They are separate yet act as a unit in the one person of Jesus. This is called the Hypostatic Union.
The following chart should help you see the two natures of Jesus "in action":
A doctrine that is related to the Hypostatic Union is the communicatio idiomatum (Latin for "communication of properties"). It is the teaching that the attributes of both the divine and human natures are ascribed to the one person of Jesus. This means that the man Jesus could lay claim to the glory He had with the Father before the world was made (John 17:5), claim that He descended from heaven, (John 3:13), and also claim omnipresence, (Matt. 28:20). All of these are divine qualities that are laid claim to by Jesus; therefore, the attributes of the divine properties were claimed by the person of Jesus.
One of the most common errors that non-Christian cults make is not understanding the two natures of Christ. For example, theJehovah's Witnessesfocus on Jesus' humanity and ignore His divinity. They repeatedly quote verses dealing with Jesus as a man and try and set them against scripture showing that Jesus is also divine. On the other hand, theChristian Scientistsdo the reverse. They focus on the scriptures showing Jesus' divinity to the extent of denying His true humanity.
For a proper understanding of Jesus and, therefore, all other doctrines that relate to Him, His two natures must be properly understood and defined. Jesus is one person with two natures. This is why He would grow in wisdom and stature (Luke 2:52) yet know all things (John 21:17). He is the Divine Word that became flesh (John 1:1,14).
1 Tim. 2:5says,"For there is one God, and one mediator also between God and men, the man Christ Jesus."Right now, there is a man in heaven on the throne of God. He 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 Jesus.
