Although He came down to our level by taking on human nature, and humbled Himself throughout His life on Earth, it was only an adding a human nature. He did not empty Himself of His divinity, but rather being divine took up a human nature in addition to His divinity.
I suppose where I see a difference is that Jesus' purpose was always divine. If He took on some finite purpose that I see as only being relevant to humans, then I'd think why? Could He be "only" human afterall, and the things He speaks of in life hereafter, does He not even believe it if He seeks finite pleasures?
It also goes against the belief that Christ came to do His Father's will (John 4:34), if He instead chose to live out His own desires. As Christ says:
- 38For I have come down from heaven not to do my will but to do the will of him who sent me. 39And this is the will of him who sent me, that I shall lose none of all that he has given me, but raise them up at the last day. 40For my Father's will is that everyone who looks to the Son and believes in him shall have eternal life, and I will raise him up at the last day."
If Christ went about anything but His divine purpose, it appears from His words that He risked loosing some who could otherwise be saved. His love for each of us is too great to let go of by fulfilling any of His own earthly desires.
