No doubt Christ is special, but how could He purchase our redemption if He did not have a 'sin nature' that could be submitted to the will of the Father?
Hebrews 4:15 - "For we do not have a high priest who is unable to sympathize with our weaknesses, but we have one who has been tempted in every way, just as we areyet was without sin."
Clearly, if he did not have a 'sin nature', He was not "tempted in every way, just as we are".

I think the question is in error: As far as redemption goes, it is the Lamb of God, without spot or blemish, which is sacrificed for us... That Blood is the "coin" of purchase/redemption. The purity of that offering is priceless because it is without sin.

There is the sticky wicket, isn't it? His temptation, and His time in Gethsemane are quite possibly the most human moments of all. One doesn't think of God being tempted or in distress...
But then, I don't have a "hypostatic union" to defend - So I can shrug my shoulders and say, "He is God. As God, anything is possible." It is a mystery which is not revealed, and I am content to leave it that way.
