Islam teaches that Allah is the creator of the universe, and the Koran is the perfect revelation of Allah to the world. This revelation was delivered to Muhammad. What do Muslims think of the Bible? Well, many of them think the Bible has been changed. Curiously, the Koran states the opposite. For example, Allah sent down “the Book, confirming what went before it; and He sent down the Law (of Moses) and the Gospel (of Jesus) before this, as a guide to mankind” (Koran 3:3). The Koran also says Allah is all-knowing, so “None can change His words” (Koran 6:115). Since Allah’s words can’t be changed and the Bible is said to be Allah’s revelation, how could the Bible have been changed?
Oddly enough, the Koran says its own text has been tampered with. It mentions wrath “sent down on those who divided (Scripture into arbitrary parts)” and people who made the Koran “into shreds (as they please)” (Koran 15:90-91). Since the text of the Koran was being tampered with during its compilation, how do Muslims know they have the right version of the Koran today?
Of course, the Koran also states that “None of Our revelations do We abrogate or cause to be forgotten, but We substitute something better or similar” (Koran 2:106). Put differently, some Muslims believe that when there is a discrepancy between two passages, the passage which was revealed later replaces the earlier one. Still, if the words of Allah never change, why would later revelations of Allah be different from earlier revelations? The Koran claims that “Had it been from other Than Allah, they would surely have found therein Much discrepancy” (Koran 4:82). Since there are discrepancies between earlier and later revelations, does this mean the Koran is “from other Than Allah?”
Here’s the deal. While Muhammad was a sinner (Koran 40:55; Koran 47:19; Koran 48:2), the Koran says Jesus Christ is sinless (Koran 19:17-19). Since Jesus is without sin, He never lied. The Koran also says the Bible is the perfect revelation of Allah (Koran 3:3), and the words of Allah can never change or be corrupted (Koran 6:115). Considering Jesus never lied and the Bible is perfect and incorruptible, everything the Bible records Jesus saying is true. Well, the Bible records Jesus Christ saying “I am the way, the truth, and the life: no man cometh unto the Father, but by me” (John 14:6). In other words, the only way to Heaven is through faith in Jesus Christ. All Muslims, according to the Koran, should be Christians.
