However.....
God alone holds the ability to judge.
Calling themselves Christians, they need to use the New Testament as well as the Old. It is written very clearly in the New Testament that the Old Testament "rules" about tit-for-tat are no longer valid with the coming of Christ.
They are simply using whatever parts of the Bible they wish to further their "cause" and get in the news, not caring that they are giving those who are not Christian the wrong idea of what Christianity is about.
I have been busy and away from the computer for several days so this is my first chance to respond.
