The god of Islam and the god of Christianity are not the same.
"The Koran asserts that the god of Islam is the God of Christians and Jews (Sura 29:46). Nothing could be farther from the truth.7
The god of Islam, Allah, is most definitely not the God of the Bible. Allah is presented in the Koran as an autocratic ruler who is aloof and arbitrary (Sura 5:40). Allah is unknowable whereas the God of the Bible is knowable (2 Timothy 1:12). Allah is impersonal, unlike the personal God the Scriptures reveal (1 Peter 5:6-7). Allah is unitarian (Sura 4:48) whereas the God of the Bible is trinitarian (2 Corinthians 13:14). Here is what the Koran says about the God of the Bible (Sura 4:171): “Believe in Allah and say not ‘Trinity.’ Cease! It is better for you! Allah is only One God. Far is it removed from his transcendent majesty that he should have a son.”
Allah is capricious (Sura 2:284), whereas the true God is trustworthy. And Allah is never anywhere presented as a god of love — which is the essence of the nature of the true God (1 John 4:7-16).
Jesus — The Koran denies point blank that Jesus was the Son of God (Sura 112:2-3). It also denies His atoning sacrifice by claiming that he never died (Sura 4:157). A substitute died for Him on the Cross. Jesus was translated to Heaven, like Enoch, where He will remain until He returns to kill all pigs, destroy all crosses, and convert the world to Islam. Jesus will marry, reign for 40 years and then die and be buried next to Muhammad in Medina.8 Jesus is characterized in the Koran as nothing more than “an apostle of Allah” (Sura 4:171).
Sin — There is no concept of sin in Islam and therefore no need for forgiveness. Shame replaces sin. Everything is a matter of honor verses dishonor.9 In the Muslim view, man does not need redemption, he only needs some guidance so that he might develop the inherently pure nature with which the Creator has endowed him. If he will be faithful in his prayers, almsgiving and fasting, God is likely to overlook his failures and usher him into Paradise.10"
