—I think the deal is this: although Jesus was God, he was also fully mortal when he was on earth, with all the normal weaknesses and temptations, and was just as subject to pain and fear as any man.—
The problem is, you can’t have it both ways. Either he was fully human, or he was special in some way that made him different from other humans. And pretty much all theology demands that he be special in some way. You can’t, for instance, both be a regular joe AND sinless, and claim to have experienced regular joeness in full.
Whether Jesus personally knew or not is beside the point. God is said to be the one making the sacrifice, and God, presumably, knew the outcome, risking nothing.
The story still seems to come out like this: God demands a debt, but it’s an odd one in the history of debts. It’s one that was never actually incurred in return for anything, but rather that he himself created people as having inherently, in addition to inherently not having any capacity to pay off the debt themselves (sort of like an indentured servant who owes more than a lifetime worth of work for his passage to the new world). After either a long unknown plan or just after it taking him millenia to realize that his servants can by the very nature he created them with never pay off their debt themselves (which for some reason makes him mad, and for some reason takes time, despite him being timeless), God decides to offer them forgiveness. But instead of simply forgiving the debt, God decides to kill himself by coming to earth as Jesus and commiting a capital crime under Roman law. After a spot of suicide by state, God for some reason feels better about the whole thing, is willing to forgive, and somehow now has powers to commune with humans that he did not have before (despite always being omnipotent).
—Tillich/Spong style theology suggests that this concept is inadequate to explain exactly what God is.—
Whatever it is, I still don’t currently believe in it as “God” much less the Christian god in particular, unless you really take seriously Tillich’s rewriting of half the dictionary to make theology safe for atheists… even when they don’t know it.
You see, even Republicans are actually Democrats, because the Democratic platform is the ground of all being.
