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:

He wasn't; he descended down to earth (previous two verses), hence the need for an [ascension](http://en.wikipedia.org/wiki/Ascension_of_Jesus), which is what [exaltation](http://www.greekdoc.com/bible/lexicon/uper.html#uperuyow) means; see also John 17:24.

Apparently a Protestant or Evangelical Trinitarian; when doing the sign of the cross, moving the right hand from the forehead to the chest or abdomen signifies Christ's descent from heaven to earth, and its move to the right shoulder, His ascent to the Father's right hand side (Matthew 26:64, Mark 14:62, Luke 22:69, Acts 7:56, Hebrews 1:3, 8:1; 1 Peter 3:22).

This is a dead giveaway, insofar both seem to befit His humanity; otherwise, in light of divine immortality, one could also ask:

> 
> If Jesus was God (the famous John1:1), why was He ~~exalted to higher position~~ *resurrected*, as if he wasn't ~~in that position~~ *already alive to begin with*?

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.
