From post #1512 by JesusRules1 -- Jesus is Creator of all things,and according to His deity the Bible says He is from everlasting,which means he has no beginning(Micah 5:2),but according to His humanity He has a beginning.
Many versions of Micah 5:2, including the Complete Jewish Version say that he has an origin. You can't have an origin if you have no beginning. This, however does not necessarily change the trinity of God. If God created The Word, He then gave The Word full power and knowledge. Not that the power was in The Word, more like it flowed from God through Him. Being like minded there would be no hesitation of power flow from one to the other, so The Word had full power and direction from God to create all that was created. This last statement then begs the question: How did He create Himself? I have been pondering this for a while and have no answer other than that The Word was always in existence. As I said earlier, some bibles use the word origin, but other use the words "goings forth", which I am beginning to believe may be more accurate.
Of course, when He came to earth He gave up much of His "Godhood" to become a man to be tempted, but He was still God in the real sense and in the traditions of the times. The first born were given full rights of the father when they became of age, although I don't know when that was. I suspect that in Jesus case it was when he became 30 and began His ministry. The father was still in charge, but if the son or father was away, the son, wherever he was, being separated from his father could make legally binding deals for the family. He therefore had the power of his father and was considered the father, in legal matters. I am sure it was a similar situation with Jesus and God, but in their case God gave Jesus the power when he needed it, because Jesus said that He could do nothing without the Father.
