There is no giving up of any powers, He said He could’ve called legions of angels to help Him at any moment. God and Jesus are one.
Jesus did not say he would himself direct angels to his side, he said he could call on /ask his Father to deliver angles to his side. Matthew 26:53 http://biblehub.com/matthew/26-53.htm
and when Jesus promised the Holy Spirit to his disciples, it was also request he would put too his Father to provide such. John 14:16 http://biblehub.com/john/14-16.htm
John 14:10 "Believest thou not that I am in the Father, and the Father in me? the words that I speak unto you I speak not of myself: but the Father that dwelleth in me, he doeth the works."
Hmmm...
You keep slapping up a bunch of partial/cherry-picked verses.
