Reader J.R. Stoodley writes;
"do you mean to say that Jesus intended to or even offered to set up an eternal earthly kingdom but the Jews rejected it, so it didn't happen?"
Well, not that I know anything, but I do believe that when Jesus said "The Kingdom of Heaven is at hand", he meant it. He wasn't just going through the motions - I don't think he did things that way.
Obviously, as God, he knew that this offer would be rejected, but that doesn't mean it wasn't a real offer.
It is a difficult subject, and I am speculating, but whereas God's overarching will can not be ultimately frustrated, his will is often frustrated and rejected in a temporal, earthly sense. It is a great mystery (one of the greatest mysteries of creation) that he allows this, but if we were not free to disobey him, then neither would we be able to freely obey him as he desires. By His sovereign will, though, He always turns these things to his own good purpose, in the end.
One can see in Jesus words, "...how often I have longed to gather your children together, as a hen gathers her chicks under her wings, but you were not willing.", that God has allowed us the unspeakable liberty of really resisting his will by our free acts.
So, just as the crucifixion - Deicide - is the most horrible crime imaginable, it is turned into an incomprehensible miracle. Yes, Jesus meant to be sacrificed for man's sins according to the prophecies of Scripture. He "set his face like flint", but still he prayed "If it is possible, let this cup pass from me".
This all gets into the tension between time and eternity, heaven and earth, and Jesus' humanity and divinity. My original post had mainly to do with Jesus' human nature as he seems to reveal it in the agony of grief he endured at Gethsemane.
Keep in mind, also, that these are the musings of one almost wholly ignorant of real theology. If I venture anywhere near heresy, I defer to better, holier minds and the teaching of the Church, and will gratefully accept patient instruction.
