I would venture to say they are not. We read about Islamic brutality every day. Most of these men probably believe they are doing what God wants them to do, and in a sense they are right. The god of this world (satan) is very pleased to see them murder their enemies. After all, the Bible says, "You are of your father the devil, and your will is to do your father's desires. He was a murderer from the beginning, and has nothing to do with the truth, because there is no truth in him. When he lies, he speaks out of his own character, for he is a liar and the father of lies." (John 8.44 ESV)
It is unfortunate but true that Islam is the most violent major religion known to man. They take the fifth satanic statement, "Vengeance is mine, no turning the other cheek" (from the satanic bible) as their own command. The Bible teaches:
Bless those who persecute you; bless and do not curse them. Rejoice with those who rejoice, weep with those who weep. Live in harmony with one another. Do not be haughty, but associate with the lowly. Never be conceited. Repay no one evil for evil, but give thought to do what is honorable in the sight of all. If possible, so far as it depends on you, live peaceably with all. Beloved, never avenge yourselves, but leave it to the wrath of God, for it is written, "Vengeance is mine, I will repay, says the Lord." To the contrary, "if your enemy is hungry, feed him; if he is thirsty, give him something to drink; for by so doing you will heap burning coals on his head." Do not be overcome by evil, but overcome evil with good. (Romans 12.14-21 ESV)As the society tells us that Islam is a peaceful religion and the world tells us to be "tolerant" of Islamic beliefs, we see the "intolerance" found in Islam- and the world for that matter. Pay attention to the reports of Mosques being blown apart and see who is doing it- not U.S. soldiers, but other Muslims.
