I've always heard it said that Jesus was "completely human" and "completely God".
How could he be both human (finite by very nature) and God (infinite by very nature)?
It's one of those difficult things to comprehend. In fact, I think we may never be able to fully understand it. Jesus is God and has existed eternally as God (John 1:1, 18) but took on the additional nature of humanity during the incarnation. He fully possesses each nature, much in a sense that each member of the Trinity is fully God. His natures are also distinct much as the members of the Trinity are distinct. For instance, Jesus as man is not omniscient (Luke 2:52, Mark 13:32). Jesus as God cannot experience death. His two natures are completely distinct yet fully and completely unified in His single person.
He was completely given to humanity, entering a sinful world, experiencing pain, loss, hardships, work, temptation, hunger, and even death. All the while, He was completely God, omniscient, omnipotent, and omnipresent. Take John 1:48, where Jesus said He saw Nathanael under the fig tree before Philip called him to come see Him.
He was completely human, bled when He was whipped, suffered the agony of dying on a cross, but He was completely God, taking the sin of everyone who would ever believe in Him upon Himself and carrying it to the grave as He died, and then bringing His own body back from the dead. No one man alone could bear the sin of all. We can't even free ourselves from our own sins.
There are concepts presented in the bible that are impossible for our human minds to understand. The Catholic and Lutheran (and perhaps others) idea of the Holy Trinity, for example, that God, Jesus and the Holy Spirit are all God is very difficult to wrap our minds around, and this is another example of things that are outside our understanding.
The word Begotten in Hebrew is translated from many different Hebrew words.
When referring to Jesus it is the Hebrew word Monogenes which means: single of its kind, only used of sons or daughters.
How did God bring forth Christ?
I am by no means capable of portraying Jesus in a few paragraphs but I will give you the best explanation that I can.
Out of the deepest echoes of God's heart, filled with the most compassion and love in existence, He spoke Jesus to us.
Jesus is God.
You see, when you divide infinity, you still have infinity. All of the fullness of God was in Christ Jesus. Completely Man, and also completely God.
How can God be man and yet still be God? Because Jesus is God in the Flesh 100%, filled with God in the Spirit 100%. The two are one, but are each their own separate entity.
Just as God empties you of your spirit and fills you with His own. Jesus had no spirit of his own, because His spirit was God in His fullness.
"Glory to you father, Glory, Glory forever and ever, Amen."
During his time in our dimension, Jesus, while remaining a person of the trinity put off his divine nature (and everything that goes with it) to become incarnate as a man:
Therefore, while on Earth, Jesus did not possess divine attributes such as Omnipotence, Omniscience, etc. What supernatural knowledge and power he wielded he did through the Holy Spirit:
Indeed, while conceived and living sinlessly in perfect obedience to the Father, he retained his own will as a person, but subjected that will to the Father; unlike his "normal" state, without God's nature he remained like-minded only by exercise of that will in obedience, no longer by virtue of sharing one nature with the Father:
So, my conclusion is that Jesus, while on earth, was wholly God in person and wholly man in nature. In his glorified state, of course Jesus is wholly God in both person and nature.
God's physical manifestation in the world through a mortal body
Do not let anyone tell you anything else. To deny Christ's divinity is to deny Christianity.
Bible texts that speak about his divinity
Matt. 11:27; 16:16;
Luke 5:20-22; 9:20;
Luke 9:58; 22:44;
John 1:14; 11:33-35; 19:28, 34;
In Rev 22:13 (NIV), Our Lord says "I am the Alpha and the Omega, the First and the Last, the Beginning and the End."
So, He is the beginning and ending. Everything starts from him and ends with him, like a Circle.
Jesus is a Divine person with a finite human nature and an infinite divine nature. The key points here are "one person" and "two natures." Person answers the question who is performing an act; nature defines what is performing the act. As such, when we read in the Gospels what Jesus said or did or where he went, we have to realize that this is God saying, doing, and going. At the same time Jesus is human and subject to the human condition: He eats, He sleeps, He can bleed, He can be killed. This is important for us all from a salvation standpoint. The Original Sin was an infinite offense because of Who was offended. The only possible reparation would have to be infinite, something only a divine person can do. Or put another way: if God didn't die on the Cross, then the sacrifice is not infinite and is therefore not able to open the gates of heaven. To say that "God died" is not difficult to understand when you realize that the person who died -- Jesus -- only died in His human nature (the soul was separated from His body). Jesus cannot be killed in his divine nature, but he was able to be killed in His human nature.
