Answer: There is a huge difference. Muslims claim to follow Allah. He is not the God of the Bible (see Q&A Feb ’02). Muhammad claimed that Allah commands Muslims to “fight against all people [worldwide] until all confess there is no god but Allah and Muhammad is his messenger.”
By contrast, Israel was not commanded to convert anyone under threat of death, nor to take over the world, but to exterminate the Canaanites because of their wickedness and to possess that specific land. It’s boundaries are stated in Genesis 15. Held captive in Egypt, Israel was restrained from invading Canaan for 400 years because “the iniquity of the Amorites is not yet full” (Gn 15:16). Only then did the evil of these people reach such proportions that God’s holiness forced Him to use Israel to annihilate them.
Muslims also point to Crusader killings in the name of God and Christ. That slaughter of Jews and Turks, however, was in disobedience to the Bible and to the teachings and example of Christ.
The murder of millions of both Christians and Jews by Muslims all through history, and today’s terrorism, are in obedience to the Qur’an, Allah, Muhammad and the example he and early Muslims set. What a difference!
