I don’t know how much time I’m going to have, Dave, so without reading everyone else’s comments, I’ll jump straight to ONE.
Maybe I’m not thinking this through deeply enough, but it seems to me that Jesus having a divine and a human nature isn’t really a problem. This is the way I see it. Jesus came to be an example for us for the way we can live when depending on Father for everything (as He did/does). Perhaps He’s been doing this always, since He goes forth from the Father always. He has that divine nature of the Father, but perhaps Father gave all of us that, in the Spirit of life He gives to each of us. I don’t know. He’s God and He came and inhabited the body (complete with human nature) that Father prepared for Him. It’s not like He was neurotic, suffering from multiple personality disorder. He lived as a man, having emptied Himself of His godhood, though still having that divine nature (as is now available to us). He lived by the power of the Holy Spirit in obedience to the Father. His advantage was to have an unfallen human nature (which of course we do not have), but to even the score, He stood in for the whole family of mankind as our representative and died on our behalf, destroying that old man once and for all. He was raised and we are raised in Him to newness of life. We have defiled our humanity and must climb out of the hole – a thing He did not do – but He is here, our shepherd, to pull us out so long as we’re willing to allow it and cling to His hand best we can. Jesus was MASTER of His body (mind, will, emotions) as we are to BECOME master of our own bodies though we do this in concert with Him and trusting Him to complete that work in us.
Think of His first miracle. He turned the water into wine. The water is still there, but now it’s infused with life and nourishment (the blood of grapes, you know) and makes glad the heart of man. AND it’s really, really GOOD wine! Somewhere around 150 gallons of it! Jesus gives life and life in abundance. So now He lives in us via the Holy Spirit and our natures are also mingled divine and human. He is special though, because He has always been with and of the Father. For us, this is an imparted nature whereas for Him it is intrinsic. Will we be like Him? Yes. What does that mean? I honestly dare not go any farther – it’s more than I know.
