The bible also refers to others as "sons of God." We are all God's children. God doesn't have to assume paternity for anything. GOD is GOD. Christians like to compact the power of God by associating God with human like qualities. And I know you will refute this statement by saying, "God made us in the likeness of him." Christians take everything too literally, one must look for the meaning. God gave us qualities that are superior to that of the other creatures of the world, thus we are in his likeness.
"And thou [Moses] shalt say unto Pharaoh, Thus saith the Lord, Israel is my son, even my first born." (Exodus 4:22),
"He [Solomon] shall build a house for my name, and I will establish the throne of his kingdom for ever. I will be his father and he shall be my son." (II Samuel 7:13-14),
"I am a father to Israel and Ephraim is my firstborn"(Jeremiah 31:9), 'long before Jesus was born', "I will declare the decree:the Lord hath said unto me [David], Thou art my son; this day have I begotten thee."(Psalm 2:7),
and "Seth, which was the son of Adam, which was the son of God"(Luke3: 38).
Do the few I mentioned have this "unique begotten son relationship"? Is Jesus still unique because he had no father?
ONLY GOD HAS DIVINE QUALITIES
Matthew 24:36, quoted below, demonstrates that Jesus was not omniscient:
(In relation to the end of the world Jesus said to them "As for the exact day or hour, no one knows it, neither the angels in heaven nor the son, but the Father only." [Matthew 24:36]
One divine quality is the ability to assign the souls their positions in the Hereafter. Jesus tells us that only God can do this. When he speaks to the mother of his disciples James and John, she asks him to promise that her sons will be on either side of him in the Hereafter:
"...But sitting at my right hand or my left is not mine to give. That is for those to whom it has been reserved by my Father." [Matthew 20:23]
Surely, when Jesus prayed in the Garden of Gethsemane he demonstrated that he was neither omnipotent nor omniscient:
"Father, if it is your will, take this cup from me; yet not my will but yours be done." [Luke 22:42]
Jesus made it clear in many, many ways that he was not God, that God is greater. Nowhere is this more definitely stated than when he spoke to his disciples about his imminent departure:
If you truly loved me you would rejoice to have me go to the Father, for the Father is greater than I. [John 14:28]
JESUS' PRAYERAs demonstrated above, and throughout the Gospels, Jesus prayed to God. This certainly argues against his being God. God would not pray to Himself.
Like Luke 22:42, the Gospel of Matthew reports that a very human Jesus became distressed in Gethsemane and turned to God for solace:
He advanced a little and fell prostrate in prayer. "My Father, if it is possible, let this cup pass me by. Still, let it be as you would have it, not as I" [Matthew 26:39]
There were times when Jesus felt the need to pray with special urgency. Luke reports that, on one occasion, Jesus prayed very hard:
In his anguish, Jesus prayed with all the greater intensity, and his sweat became like drops of blood falling to the ground. [Luke 22:44]
Jesus also prayed to God that the people might believe in him as God's messenger. This specifically defines the role of Jesus as deliverer of God's message:
...Jesus looked upward and said, "Father, I thank you for having heard me. I know that you always hear me but I have said this for the sake of the crowd, that they may believe that you sent me." [John 11:41-42]
One of the most compelling pieces of evidence that Jesus was not God is in the way that he taught the disciples to pray:
One day he was praying in a certain place. When he had finished, one of his disciples asked him, "Lord, teach us to pray, as John taught his disciples." He said to them, "When you pray, say: `Our Father in heaven, hallowed be your name, your kingdom come, your will be done on earth as it is in heaven. Give us today our daily bread, and forgive us the wrong we have done as we forgive those who wrong us. Subject us not to the trial but deliver us from the evil one.' " [Luke 11:1-4] [Matthew 6:9-13]
Note that Jesus taught us to pray to the Father, our Creator, not to himself. In fact, he did not mention himself in any way, nor did he indicate that we should pray in his name. His instructions were very specific-we are to pray to God alone.
This would not be the case if Jesus himself were God.
