What are the differences between Muslim and Christian beliefs about God?
The word “Allah” is the Arabic word for God, the word used both by Arabic-speaking Christians before the birth of Mohammed, and by Arabic-speaking Christians today. To a devout Muslim, Allah is in many ways similar to the Christian God. Allah is holy, just, infinite, and all-knowing. Jews, too, worship a holy, infinitely powerful God, and share Christian respect for the Old Testament. The Qur’an portrays God as a just and merciful judge, but doesn’t teach that human sin and distress cause Him suffering 1 . It emphasizes the incomprehensibility of God more than His holiness 2 and love 3 . Christians believe that biblical revelation is progressive 4 , fulfilled in Christ. Although the Old Testament describes God’s supreme love ( Exodus 34:6 ; Psalm 86:5; 103:13 ; Isaiah 49:14-18 ; Jeremiah 31:10-20 ; Ezekiel 34:22-31 ; Micah 7:18-20 ; Hosea 2:14-16 ) at times its portrayal of God is troubling.
