Does this mean, then, that God is so fed up with Israel that he'll have nothing more to do with them? Hardly. Remember that I, the one writing these things, am an Israelite, a descendant of Abraham out of the tribe of Benjamin. You can't get much more Semitic than that!
So we're not talking about repudiation. God has been too long involved with Israel, has too much invested, to simply wash his hands of them. Do you remember that time Elijah was agonizing over this same Israel and cried out in prayer?
God, they murdered your prophets, They trashed your altars; I'm the only one left and now they're after me!
And do you remember God's answer? I still have seven thousand who haven't quit, Seven thousand who are loyal to the finish.
It's the same today. There's a fiercely loyal minority still - not many, perhaps, but probably more than you think.
They're holding on, not because of what they think they're going to get out of it, but because they're convinced of God's grace and purpose in choosing them. If they were only thinking of their own immediate self-interest, they would have left long ago.
