Rom 9:"14 What then shall we say? Is God unjust? Not at all! 15 For he says to Moses, I will have mercy on whom I have mercy,and I will have compassion on whom I have compassion.[f] 16 It does not, therefore, depend on man's desire or effort, but on God's mercy
Hunter preached on Chapter 9 Sunday. Powerful stuff. A bit difficult ot wrestle with though, no doubt. This, to me, dispels any notion of free will as it pertains to salvation. The Israelites had every advantage, saw God working physically, and yet still did not believe. That's why I always find the atheist that tells me, "Show me proof." funny.
Now the mistake that historical Christians made is assuming that "the Church" is the new Israel and that Israel has fallen out of favor. Either that or there's the new belief that as American Christians it is our responsibility to prop the "nation of Israel" up to fulfill prophecy. Silly us. If God wants a whole nation, He can do what needs doing. "Israel" is simply whatever group of people God chooses.
