Islam teaches that the true God is the Muslim deity, Allah. All other views of God are false because the Koran teaches, “The true religion with God is Islam.”[1] The Koran emphasizes of Allah: “There is no God but he, the Living, the everlasting.”[2]

But who is Allah? Is he anything like the God of Christian faith? As we will see, the Muslim God is entirely different from the biblical God. First, the Koran stresses that Allah is one person only: “They are unbelievers who say, ‘God is the Third of Three.’ No god is there but one God. If they refrain not from what they say, there shall afflict those of them that disbelieve a painful chastisement.”[3] Here, the Koran emphasizes that Christians are unbelievers because they accept the historic Christian doctrine of the Trinity.[4] But, as we fully documented in our Knowing the Truth About the Trinity (Harvest House, 1997), the Bible unmistakably tells us that God has revealed Himself as a triune Being, as One God eternally existing in three Persons—Father, Son and Holy Spirit (Mt. 28:19; Jn. 1:1,14; Acts 5:3-4).[5] Although many Muslims believe otherwise, Christians do not believe in three gods. This idea is a clear misrepresentation of Christian belief. Christians are not polytheists, who accept three gods, but monotheists who believe in one God.
