You are mistaken. Let me offer just one illustration from the Christian Bible. There are others but you can locate them on your own.
Deuteronomy 20: 17 But thou shalt utterly destroy them; namely, the Hittites, and the Amorites, the Canaanites, and the Perizzites, the Hivites, and the Jebusites; as the LORD thy God hath commanded thee:
I believe the reason for these suggestions from the Koran and the Bible is because the spiritual advisors knew that one could not co-exist with negative influences and remain true to Gods teachings.
No, you are.
Ripping a verse from its context proves only the inadequacy of your reading.
First, there are no living Hittites, Amorites, Canaanites, Perizzites, Hivites or Jebusites - so even if this command applied to Christians, it would be purely academic.
Of course, this was a command issued specifically to the Israelites and the command was specifically to be carried out in the geographic confines of the land of Israel.
It simply doesn't apply to Christians, and to try to replicate it as a doctrine would be to repudiate the New Testament, thereby renouncing Christianity.
The Koran injunction is not confined to any specific time, place or target but it applies to all Muslims always regarding any unbeliever.
The only exception is that a Muslim is not allowed to kill an unbeliever if the Muslim caliph has officially extended that unbeliever his protection in exchange for monetary tribute.
Since there is no caliph anymore, no restrictions apply.
MosesKnows very little it seems, this verse was taken out of context. You are right in one sense about the inability to coexist but GOD was also using the weakest most pathetic people in the world to deliver judgement to nations that had decended to unimaginable depths of perversion and sinfulness (child sacrifice, bestiality, etc). After Israel took the land THE LORD commanded them to take and gave to them, these types of verses fall off.
Where in the NT do you find commands to commit violence?
You don't because GOD in the old testament times used the physical to illustrate the Spiritual in an attempt to get HIS people to start looking forward in faith. Jesus fulfilled that foreshadowing and showed us how to look to the spiritual. Now we defeat our enemies (who are spiritual) with spiritual weapons. The bible must be taken in its full context which means a verse here and a verse there is a poor reflection of the true message contained in the scriptures.
You left out something crucial. The reason.
Not because of who they were but for their abominations.
Their abominations were such that today anyone doing the same- child sacrifice, etc- would merit the death penalty.
