Question: I was a trinitian, until I discussed with JW. I still believe in Trinity cause there're many verses back this up(including Mat 28:19) But I wondered
According to Phil 2:9 and some other verses. Jesus was exalted. If He was/is God, why after resurrection He was not only resurrected but also exalted to higher position (as if he wasn't in that position)?

Edit :
I meant, God the Father exalted Jesus to be on the right hand after His obedience, as if He was an angel (Michael Arcangel) before then now be the first born aka the heir of the authorities and kingdom of His Father.

Edit 2 : oh may, this Jw doctrine almost make me able only understand verses like Jw thinks. That, as if I was blind to the whole context of the chapter and story and bible.

Answer: 
The humbling of the Son of God, and then his exaltation in humanity, is explained in Hebrews 2:9. The literal translation demonstrates the sequence of events :

> 
> ... but who little some than angels made lower we see Jesus on account of the suffering of the death with glory and with honour crowned
> 
> 
> 

This is the Englishman's Greek New Testament literal interlinear but can also be seen, very much the same, in the [Biblehub literal interlinear](https://biblehub.com/interlinear/hebrews/2-9.htm).

Being made lower than the angels, that is to say, coming from heaven and having already humbled himself ('voiding' himself as we read in Philippians 2:7) Jesus, in humanity, went further and submitted to suffering and death - in humanity.

For this cause, as the writer to the Hebrews makes clear, that is to say on account of the suffering and death he endured in his humanity, he is, upon resurrection, highly exalted.

The exaltation is in honour of what he, himself, in humanity, endured in his humanity, and is not automatically applied due to his previous glory and honour prior to incarnation.
Philippians 2:9 indicates that Jesus was rewarded for the great sacrifice of humbling himself even to death on a cross. If he were merely exalted back to the place that he held before, what is the reward in that?

He was also given the reward of a name that is above all names. It is not the name of Jesus, Yeshua, Yehoshua or any similar earthly name. He already had that name before his death. It is a new name referred to in Rev. 19:12.

As is the case in so much about the nature of God, we are not given much detail about all that Christ’s exaltation entailed. Daniel 7 sheds a little additional light.
