To your question is Islam a religion of war or of peace? The answer it is a religion of war. I have read the Quran or Koran and it calls Muslims to crucify, decapitate, etc someone if they do not convert to Islam. While not all Muslims are part of these Islamist extremist groups the beginning of Islam to present day has always been violent. Our president sadly does not get this or gets this, but wants to pull the same thing on Christians. As far as I know from reading the Quran, there is only one verse where the Muslim is called to love their enemies. Otherwise they are called to do alms, fast (Ramadan), take a pilgrimage to Mecca, pray five times (I think it is) to Mecca, and say the confession of the Islamic faith, which has many variants but one says, "There is no God but Allah and Mohammed is his prophet." According to the Quran the unbeliever (infidel or kafir) has four options. Either they can pay the jizya (the tax) and by doing so become a second class citizen in what would be called dhimmitude, flee, convert to Islam, or be killed. Amazingly, not all Muslims realize what their Quran and the hadiths (I think they are sayings) of Muhammad say which show that Islam is not a religion of peace but of war. In fact even the Bible hinted that something is wrong with Islam, when it mentions Ishmael in a prophecy and it says that he will always be at war with his brothers. In fact Galatians 1, knocks out JWs, Mormons, ''Christian'' Science, Islam and all other false religions with a phrase that basically says don't listen to an angel if what they say is not what the Bible says. Also, thankfully not all Muslims kill people. In fact those who are part of ISIS or Islamic State, Boko Haram, Al-Shabaab, Al-Qaeda, Moro Islamic Liberation Front, Al-Nusra, and many others are really followers of the teachings of Muhammad and not followers of the triune deity which Jesus, the Son is part of. The Trinity, which consists of God the Father, God the Son (Jesus Christ), and God the Holy Spirit (who is a he and not an it or force as the JWs call him, even Jesus referred to the Spirit as a he). So Pat Robertson is correct (he is not always correct but if you were to ask a lot of Muslims in the Middle East, what Islam is, a lot of them even if they did not kill people, would mention what the sayings of Muhammad and the Koran say which shows that Islam is violent by its very nature, as quoted in the The History of the Decline and Fall of the Roman Empire by Edward Gibbons, it is a religion of the sword and the book in the chapter about Islam and its origins. But though it is a religion of war, the best way to reach Muslims for Christ, is to simply love them and talk to them just like a regular person, then they might open up more and start asking questions, and who knows they might accept Jesus Christ as their personal Savior and sovereign Lord and especially accept him as the Son of God (a concept that is goofed in their Koran, which thinks that Mary is part of the Trinity, which she is not and think is about three gods when it is about one God in three Persons). God bless. Have a beautiful day!
