There are some people who think that God gave up on Israel a long time ago. This is NOT true. "The gifts and calling of God are irrevocable." God's relationship with Israel continues. The prophet Zechariah spoke of this continuing relationship and we do well to listen to what the Lord says through him.
There is much to consider in this message. Many examples of how God deals with those who "touch" Israel are recounted. These can be found in their entirety in 'Eye to Eye: Facing the Consequences of Dividing Israel' by William R. Koenig and John McTernan and 'Israel Omen' and 'Israel Omen II' by David Brennan.
