Waking up to our existence has us as humans led to the common error of either rejecting the spiritual nature of our existence or the physical nature of our existence. Talking with unbelievers and I have ran into a lot of skeptics who don’t believe we as humans are anything other than physical bodies and the skeptics who believe that we are nothing but spirits who think that we exist as physical bodies, but when in reality we are only spirits. The truth of the matter is that the only way to account for all of the facts at hand is that we humans are 100% physical and 100% spiritual in a mystery but that we must accept this as true because it is the only way to logically account for all of the evidence. These two different spheres of our existence coexist but do not mingle to form a third entity but certainly have an effect on each other. The spirit is not dependent on the body to exist, and the body can seem to exist without the spirit as at least seems to be in the case of those who are comatose.
Sometimes because we are body and spirit there are things that are said of us that can be both true and not true at the same time because they are referring to an attribute of either our spirit or our body but not necessarily to both. For instance it can be said of me that I am weak in my body even though it can also be said of me that I am strong in my spirit. It can be accurately said of me that I am mortal because my body will die even though it would be accurate to say that I am immortal because of the eternal life that my spirit has in Christ. Moreover, there are some acts which purely belong to my spirit such as thinking and some attributes that are purely physical such as when I eat. Looking at the complexities of the interaction between our own physical bodies and our souls can be helpful especially when looking into such mysteries as the incarnation of Christ.
From the Scriptures we learn that Christ has in reality a physical body. The Scriptures address in many different ways the physical reality of who Christ was which was important for the Apostles to do because of the early Gnostic heresy which taught that Jesus only appeared to have a body. But Jesus had a real body that went through all of the physical problems and pleasures that we do. Meanwhile, as a spirit the Scriptures teach that Jesus was truly God. As the Messiah and the Savior Jesus had to be God since the Old Covenant revealed that the Messiah would have a real body, would be the savior of the world, and which revealed that only God is savior and that there is no other. So from the Old Covenant it was revealed that the Messiah would have to be God and Man and in the New Covenant we have the history recorded of when in time God became man. Jesus is only one person, and it would be a mistake to think that there was some sort of false dichotomy between the Jesus who was man and the Jesus Who is God. The Scriptures reveal that Jesus is one. Never is there even a clue that the Jesus who was man is different from the Jesus Who is God.
In Philippians 2:5-11 we have it recorded that:
Php 2:5-11 Have this mind among yourselves, which is yours in Christ Jesus, 6 who, though he was in the form of God, did not count equality with God a thing to be grasped, 7 but emptied himself, by taking the form of a servant, being born in the likeness of men. 8 And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross. 9 Therefore God has highly exalted him and bestowed on him the name that is above every name, 10 so that at the name of Jesus every knee should bow, in heaven and on earth and under the earth, 11 and every tongue confess that Jesus Christ is Lord, to the glory of God the Father.
Here we have it clearly revealed that Jesus is explicitly both God and man in what theologians term a hypostatical union. It is called a hypostatical union because Jesus did not just merely appear to be a man He was a man; and Jesus did not merely appear as God but He was God. Jesus was not a poltergeist. Jesus was not some new god alien to the Jewish faith, but He was Yahweh in the flesh and the only true extension of the Jewish faith and any rejection of Jesus is tantamount to a rejection of Judaism.
The mystery in Christ is that being a man He was subject to the limitations of the flesh and that He learned and that He was ignorant of things and that He was born in history while being the author of all things, He knew all things, and existing from eternity. When Christ ate He ate as a man and He ate as God. When Christ slept He slept as man and He slept as God. Everything that He did involved His whole being and it is this mystery that accomplishes for us exactly what we needed Him to do. As a person He was subject to all of our limitations and was able to fulfill for us the requirements of the Law so that we could enter into the fellowship with God through faith in what He has done on the cross and share in His resurrection life today. In Jesus we have everything that we need and could want.
