“We” have not turned our back on Israel. Certain leaders have, and their followers. I, for one, have done no such thing, and I doubt you have either. We have no control over what has been done to Israel by these leaders.
I know where you are coming from. That’s why I phrased it “we as a nation”. God knows every nation and everyone who has supported and is currently supporting Israel. The people in the Old Testament suffered because of unGodly leadership. Let us pray that our new leaders will keep their eyes focused on Jesus to refrain from any missteps.
