That question, “Do Muslims worship the same God as Christians?” is not a new one, but has been in the Christian news (at least) recently over the controversial suspension of a black female professor at Wheaton College. I haven’t written specifically on this topic, though I touched upon it in Does DA: Inquisition’s Imshael have anything to do with Ishmael and Islam? In that article I point out how Islam rejects God’s plan for humanity, as provided by God in the Old Testament through Isaac, and openly celebrates this rejection through their holiday of Eid Al-Adha. How can it be claimed that Muslims worship the same God when they reject biblical scriptures and even God’s plan for humanity? As any bible student knows, God’s plan is interspersed throughout all of the Old and New Testaments, so to reject it and then claim you worship the same God makes no sense. Yet the Wheaton professor, besides showing solidarity with the repression of women (which is not biblical), claims that Muslims worship the same God as Christians.
One could say, “Well, it’s the same between Jews and Christians. Jews would say we don’t worship the same God.” Many Jews no doubt say just that, but there’s a big difference. Christians don’t change the original scriptures given to the Jews, but embrace them and seek to keep them pure. Muslims, on the other hand, claim the scriptures have been altered and they are now the only ones that have the truth (which is cultish).
Also, while Christians believe Jesus is the promised Messiah based on the original scriptures, Jews simply reject him as The One God spoke of; both groups, to reiterate, look to the same unaltered scriptures. Muslims both reject the scriptures (old and new testaments) and the Christian messiah. And, both in Muslim and Western countries (ie, “honor” killings), people are often executed for rejecting Islam after having grown up in that faith. This practice–forced belief and execution for not believing–is in no way scriptural or of God. God gives us a choice to believe or not, and this concept is also at the very heart of who God is and is integral to His plan for humanity and future events/conditions as well (who enters heaven, who enters hell, redemption of creation, etc.).
God never left it in the hands of men to force others to believe, and He doesn’t give man the authority to execute other humans over nonbelief. He only gave man the authority to execute other men for the crime of murder (this authority is given to governing bodies, not individuals). The Muslims who premeditatedly kill others for nonbelief, then, are committing murder and deserve what God commanded. He makes all humans in His image and no man has the right to murder one of His human creations (Genesis 9:5-6). (Of course, all of this applies to anyone, and any “Christian” in the past who has ordered the execution of others over heresy, say, is just as guilty as anyone else of murder.)
I do agree with what CS Lewis conveyed in The Last Battle, however. Some people can worship God in adverse cultures. God calls them and they answer, but they are caught in a situation that keeps details of the faith away from them, at least for a time.
If you’re interested in reading further on this issue of the Christian vs Muslim God, Christian philosophy professor William Lane Craig had addressed it recently in his Questions of the Week column: Do Muslims and Christians Worship the Same God?
In addition, Westerners have been getting more of a taste of Muslim teachings and practice through recent events in Europe (“uncovered” females don’t belong to anyone and are fair game for sexual assault), and I have provided many links in Raping of Women and Children Now Allowed in the West; Why Not, Eh? (A friend of a friend of mine was murdered many years ago for bathing in an isolated pool of water, or so she thought, in a Muslim country. No concerns or questions asked, just shot and killed from a distance by someone who saw her. Since men under Islam either are not obligated to control themselves, or “can’t,” women must do what they can to not be raped or murdered.)
If you think this kind of thinking is only from cultures that have older traditions that remain after Islam has been accepted, please see Female Hajj Pilgrims to Saudi Arabia Sent Back Home. “O Prophet! Tell your wives and your daughters and the women of the believers to draw their cloaks all over their bodies that they may thus be distinguished and not molested” (Koran 33:59). These pilgrims in Saudi Arabia were covered, yet they still could not do their religious duty under Islam because they had no accompanying males to protect them . . . from what? From other males molesting them, of course. And these are Muslim women, covered . . . In stark contrast, the God of Christians and Jews expects men (and women) to put effort into not sinning, and thus controlling themselves. We are not to harm others through sin, and if we do, the blame is on us, not on our (animal?) nature or on others for “tempting” us.
