Some of you seem to be getting hooked-up on the word, "earned."
Have I made a correct assumption? If so, then I submit that it seems to come two ways:
One, that He completed His task here successfully, and earned the right to represent us by being the Firstborn, resurrected of God.
And, two, that He earned Immortality for us.
We already know that He never claimed to do anything except what He saw the Father doing. So that certainly seems to imply that He was not operating freely as the omnipotent God, walking around with some flesh hanging on His All-Powerful energy.
Is there anyone here willing to deny that He divested Himself of His previous powers to actually BECOME a man? Or do you feel He just LOOKED like a man, and retained all of His powers? He even said on the cross that He wouldn't just blink His eye or wave His hand to destroy those people, but rather, as the man He still was, He would actually have to call for an army of Angels to do that for Him.
