Philippians 2:5-9 (Good News Translation)
This passage is about the nature of Jesus Christ - about how I believe he became co-equal with God The Father.
5 The attitude you should have is the one that Christ Jesus had: 6 He always had the nature of God, but he did not think that by force he should try to remain equal with God.
What this is saying is that we should be more like Jesus. It also says that he always was divine, for as long as he existed. Meaning that since the time he was begotten he was divine.
Basically, this is to say that he is consubstantial with God - a being formed (not created) out of the divine essence that has always existed (as opposed to the mundane essence which was created out of nothing - that humans are made from)
Since he was begotten, he has always been a divine being! - as he was begotten by a divine being (God The Father)
7 Instead of this, of his own free will he gave up all he had, and took the nature of a servant. He became like a human being and appeared in human likeness.
So, as a divine being he chose to became fully human - he came down to Earth to serve humankind, rather than rule over us from above. He chose to humble himself and come down to Earth and live amongst humans as a human!
A divine being became a man. This is the incarnation.
And I think that he knew that his adventure down on Earth would come to a painful and bloody conclusion. Although it wasn't really a conclusion - it was just the beginning!
8 He was humble and walked the path of obedience all the way to death— his death on the cross. 9 For this reason God raised him to the highest place above and gave him the name that is greater than any other name.
I think that this means that because he died on the cross he was made co-equal to God The Father. On account of his sacrifice - being tortured to death for our benefit
I think that before this he was always divine in nature but that having risen from the dead (after being killed) he was crowned King of Creation and made co-equal to God The Father, as part of the triune Godhead.
I think his time on Earth was to prepare him and make him human - so humans can better relate to God. Basically, he became the human face of God who accustomed himself to being human by living as a human. That's why The Word became a man!
That's what I think this scripture implies.
So, basically, I'm saying that Jesus was begotten and first of all became The Word, who had a part to play in creation. Then, he was incarnated as a human being. Named Jesus. He then died, rose from the dead and ascended to Heaven. Only then did he become part of The Holy Trinity, a co-equal to God.
After Jesus's ascension The Holy Trinity was completed and Jesus came of age.
And he shall be coming back at some point, too!
That's what I think, anyway!
