The Deity of Jesus - A Scientific Analogy
Important To Believe
I've spent years trying to wrap my head around the deity of Jesus; how He could be fully man, yet at the same time, fully God. Understanding and believing the doctrine of Christ's God-manhood is critical to the faith of Christianity. Some humanistic teachers such as Tony Campolo have written and would have you believe that "Jesus was God because he was human" (A Reasonable Faith). Furthermore, those belief systems that do not believe in the deity of Christ are considered cults (Mormonism, Jehovah's Witnesses, and others) when viewed from a Biblical perspective. If Jesus was not God, then the work he did on earth and especially the work of the cross would have absolutely no power to forgive sin and redeem mankind back to fellowship with God.
Modern Means
He was called both the "Son of Man", and the "Son of God" throughout the New Testament. The doctrine itself is quite inarguable, so I am going to make an attempt to demonstrate exactly how Jesus can be concurrently both man and God. This is simply an analogy to help explain how Jesus can be both God and Man. This may be a bit too scientific for some of you, but bear with me, it all works out. Please do not take this to mean that the biological explanation given herein is what happened in the conception of Jesus, the Bible doesn't really say definitively, except that the Holy Spirit came over Mary and the power of the Most High overshadowed her. I believe that Jesus was conceived supernaturally, not biologically. Teaching that God the Father had intercourse with Mary in order to conceive Jesus would be absolute heresy.
23 + 23 = 23
Remember 7th grade biology, when we had that chapter in the textbook about genetics, chromosomes, etc.? At the chromosome level, we (as in, human scientists) have observed what happens when the reproductive cells of a male and a female are joined. Fertilization of a female egg is defined by the joining of 23 chromosomes from the mother's cell, and 23 chromosomes from the father's cell. Without getting too geeky, we simply need to understand that in the case of chromosomes, 23+23 does not equal 46, it equals 23. The product of that 23+23=23 formula nevertheless concludes that we are made up of 100% of our father and 100% of our mother. In a nutshell, to understand this, is to understand exactly how Jesus can be both God and man.
An Note On Jesus' Human Lineage
It was required by Jewish law that the Messiah come from the blood line of Judah (and more specifically David). The first 16 verses of Matthew runs through that bloodline, all the way back to Abraham, and the last name mentioned in the lineage is Joseph, but he wasn't Jesus' father. Well, if you think you'll try to say that Jesus isn't God or the Messiah because of this, God, in his infinite wisdom, has that one covered too. In Luke 3:23-38, Luke details a very different lineage. Most Bible scholars agree that this is actually Mary's lineage (attributed to Joseph by marriage of course, considering the culture), and to sweeten the deal, it goes all the way back to Adam...that's 77 generatations from Adam to Jesus, by the way, interesting number. So in conclusion, not only is Jesus' adoptive father Joseph from the line of David and Judah, His biological mother Mary, is as well.
