In Romans 1:20-23, Paul assures us all that every man, inescapably, can do one of only two things concerning his ultimate commitments: he can either worship the Creator or the creature. Naturally, the Creator God that Paul had in mind was Yahweh, revealed to be one God in three persons in both the Old and New Testaments. Paul goes on further to claim that if you do not worship that particular Trinitarian God, you will become vain in your reasonings (Rom. 1:21).
Now, many Christians are familiar with how unbelieving thinking becomes futile when you are dealing with a materialist, naturalist, relativist, or subjectivist. None of these ultimate perspectives can truly account for the laws of logic, moral absolutes, human dignity, or any other form of truth. But when it comes to other religious worldviews, especially Mormonism and Islam, some Christians may be tempted to think that we must now switch our methodology in order to be able to give a defense for the hope that is in us (1 Pet. 3:15).
But Paul makes clear that this is not the case. As Christians, we are not defending “theism in general” when we defend the faith, because if we were we would at some level be defending the worship of false gods, such as Molech (Lev. 18:21). No, it is the particular God revealed in both the OT and NT whose name we defend. Muslims, like any other unbeliever, become “vain in their reasonings” if they consistently reason out the presuppositions of their Islamic worldview.
But just how does show this? Like with any other unbeliever, we “answer him according to his folly, lest he be wise in his own eyes.” (Prov. 26:5) What does the unbelieving fool believe, if he is Muslim? The Koran, of course. So let’s take a look at what exactly the Koran claims.
First, we should note that the Koran clearly claims that Allah is the God of the Old Testament and New Testament. “God it is who hath created the heavens and the earth and all that is between them in six days; then ascended His throne.” (Koran 32:4) The Koran also strenuously claims to be consistent with prior revelation, the OT and NT. “For he it is who by God’s leave hath caused the Koran to descend on thy heart, the confirmation of previous revelations, and guidance, and good tidings to the faithful.” (2:97) And “Say: ‘We believe in God, and in what hath been sent down to us, and what hath been sent down to Abraham, and Ishmael, and Isaac, and Jacob, and the tribes, and in what was given to Moses, and Jesus, and the prophets, from their Lord. We make no difference between them. And to Him are we resigned (Muslims).” (3:84) Other verses that teach the same are 5:48, 10:37, 38:27, 41:45, 46:12, and 98:1.
But the Koran then goes on to very clearly and explicitly deny that Jesus is the Son of God. “And they say, ‘God hath a son:’ No! Praise be to Him!” (2:116), “O ye people of the Book! overstep not bounds in your religion; and of God, speak only truth. The Messiah, Jesus, son of Mary, is only an apostle of God… say not ‘Three:’ (there is a Trinity)— Forbear — it will be better for you. God is only one God! Far be it from His glory that He should have a son!” (4:171) Several other passages reflect the same theology, such as 3:151, 5:17, 5:72-3, 10:68, 16:86, 18:4-5, 39:4, and 112.
But given the Koran’s own stated commitment to prior revelation, we must reckon with the standards given in Deuteronomy that deal with claims to revelation subsequent to Moses. “If a prophet or a dreamer of dreams arises among you and gives you a sign or a wonder, and the sign or wonder that he tells you comes to pass, and if he says, ‘Let us go after other gods,’ which you have not known, ‘and let us serve them,’ you shall not listen to the words of that prophet or that dreamer of dreams… You shall walk after the Lord your God and fear him and keep his commandments and obey his voice, and you shall serve him and hold fast to him.” (Deut. 13:1-4) In other words, any prophet must be able to perform a miracle, but even if he can you must not follow him if he teaches contrary to prior revelation.
The Bible clearly teaches Jesus is God. Just a handful of examples are 2 Pet. 1:2, Tit. 2:13, and 1 Cor. 8:6. Thus Muhammed on the one hand teaches that the Koran is consistent with the Bible and yet makes very explicit claims that are contrary to what the Bible actually teaches, such as denying the deity of Jesus. In other words, the Muslim believer becomes “vain in their reasonings” because the Koran ultimately teaches that the Koran itself must be rejected. So the Muslim is left adrift with no certain knowledge and no revelational foundation to account for human dignity, moral absolutes, and the laws of logic. Thus, if one is to be a good Muslim and believe all things the Koran teaches, then that Muslim must ultimately reject the Koran and accept the Bible as the only authoritative revelation from God.

Five questions I would like to ask Muslims
1. How exactly do you reconcile what the Bible says about Jesus and what the Koran says?
2. On what basis do you reject the book of Mormon?
3. Exactly what do you do with the most violent passages of the Koran, such as Suras 2, 5, and 9?
4. Ultimately, should the Muslim faith be spread with peace or violence?
5. If you could get away with it entirely, would you simply try to persuade someone who obstinately does not submit to Allah, or would you kill him?
