The Muslim world would have us believe that they follow the same God we do but they simply call Him by another name. Their view is that God’s blessings promised through Abraham come through Ishmael and not through Isaac. There are several reasons why we can affirm that we do not serve the same God as the Islamic world.
The most obvious one is that they see all Christians as atheists. Their philosophy of jihad (a holy war) is directed against those who believe in the God of heaven. This in and of itself shows that the One in whom we believe is not the one in whom they believe. We are atheists to them, and an atheist is one who does not believe in God.
There is a second reason why Christians and Muslims do not serve the same God (even though some would have you believe they do). The God whom I serve is described in these words, “For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life” (John 3:16). Allah did not send a son to die for me! Allah did not make provision for my salvation through that Son! Allah does not promise everlasting life through that Son!
A third way to know that Allah is not Jehovah is to contrast the “primary prophet” of Allah with the “primary prophet” of Jehovah. Study the life of Allah’s prophet, Muhammad, and you see a marked contrast between Allah and Jehovah. The founder of Islam is renowned for his army of thousands fighting against the enemy. He also had eleven wives and several children. Contrast this with Jehovah’s Prophet whose “army” “…beat their swords into plowshares, and their spears into pruning hooks” (Isaiah 2:4). Contrast this with Jehovah’s Prophet who honored the sanctity of marriage between one man and one woman for one lifetime (Matt. 19:4-6).
The final way of knowing that Allah is not God is to look at the devoted followers of Muhammad and the devoted followers of Jesus. The one believes in the jihad, the holy war. The other believes in peacefully touching the hearts of every man with knowledge of a loving God. The one is out to destroy the unbelievers, the other is out to save them. The one believes in retaliation, the other in turning the other cheek.
Do not be deceived! Allah is not Jehovah. To believe in one is not to believe in the other. There is an eternal difference!
