How should Bible-believing Christians align themselves in the Jewish-Palestinian conflict?
There are biblical reasons for treating both sides with compassionate public justice in the same way that disputes should be settled between nations generally.
In other words, the Bible does not teach us to be partial today to Israel or to the Palestinians because either has a special divine status. Israel has a unique place in God's plans, but this status does not warrant a claim, at the present time, to divine prerogatives.
