Comparing Christianity to Islam

What the Bible says about God: What Islam says about God:
There is one true and living God, who exists as three distinct, co-equal, co-eternal persons: Father, Son and Holy Spirit. While the Bible is clear that there is one God (Deut.6:4), the Scriptures also call the Father, Son and Holy Spirit God (e.g., John 20:28; Acts 5:3-4), and in some places the three persons of the Godhead are depicted together (Matt. 3:16-17; 2 Cor. 13:13; Eph. 1:3-14; 1 Peter 1:2). God is personal, knowable, approachable, and loves all people. The one true God is Allah. He is a distant God, unknowable and unapproachable. He does not love all people, only those who do well. He is the author of evil as well as good since he predestines all things. He is not triune but singular, and no partner is to be associated with him. To associate a person to Allah – such as by calling Jesus the Son of God – is to commit the unpardonable sin known as shirk.
What the Bible says about Jesus: What Islam says about Jesus:
He is the virgin-born Son of God, conceived by the Holy Spirit (Isa. 7:14; Matt. 1:18-25; Luke 1:35).  He is the eternal God, the Creator, co-equal and co-eternal with the Father and Holy Spirit (John 1:1-14; Col. 1:15-20; Phil. 2:5-11; Heb. 1:1-13). Jesus died for our sins (1 Cor. 15:3), rose physically from the dead (Matt. 12:38-40; Rom. 1:4; 1 Cor. 15:4-8; 1 Peter 1:18-21) and is coming back physically and visibly one day (Matt. 24:29-31; John 14:3; Titus 2:13; Rev. 19:11-16). He was one of God’s prophets or messengers, but inferior to Muhammad, who brought Allah’s final revelations to man. The Koran denies that Jesus is the Son of God, and any Muslim who believes in the deity of Jesus has committed the one unforgivable sin called shirk – a sin that will send that person to hell. Muslims do believe Jesus is the Messiah, was born of a virgin, lived a sinless life and is coming back one day – to establish Islam throughout the earth.  They do not believe He died on the cross, but was called to heaven by Allah.
What the Bible says about the Bible: What Islam says about the Bible:
The Bible is the inerrant, infallible, inspired Word of God, and is His sole written authority for all people  (2 Tim. 3:16-17; 2 Peter 1:20-21). The Bible is corrupted and untrustworthy. Islam claims the Koran is the literal Word of God, received supernaturally by Muhammad from the angel Gabriel. It supersedes the Bible, which also was given by Allah. The Koran does assert, however, that the teachings of the Koran are in harmony with those of the Bible: “We have sent down to thee the book (the Koran) with the truth, confirming the Book (the Bible) that was before it, and assuring it.” Yet the Koran and the Bible clearly contradict in countless ways. For example, the Koran teaches a unitarian God; the Bible, a Trinitarian God. The Koran says Jesus was just a man; the Bible, that He was and is God incarnate.  The Koran stresses salvation by works; the Bible, salvation by grace through faith in Christ.
What the Bible says about salvation: What Islam says about salvation:
Christ’s death at Calvary completely paid our sin debt so that salvation comes by grace through faith in Jesus (John 3:16, 5:24; Rom. 4:4-5; 1 Cor. 15:1-4; Eph. 2:8-9; Titus 3:5). The Koran teaches, “The true religion with God is Islam.” This means salvation is achieved only through submission to the teachings of Islam. Forgiveness is based on good works and Allah’s choice of mercy. The Muslim’s chances for heaven are good if he or she: 1) accepts the Muslim God Allah and his apostle Mohammad; 2) does good works and all that is required of him by Allah; and 3) is predestined to Allah’s favor. Islam teaches that Christ was neither crucified for our sins nor resurrected; therefore salvation cannot possibly be attained through faith in Christ. [According to Islamic tradition, Jesus was called into heaven and Judas was crucified in His place.] In short, the Muslim concept of salvation is Allah’s predestination. The Koran teaches, “All things have we created after a fixed decree …” Further, “God leads astray whomsoever He will; and He guides whomsoever He will.”
What the Bible says about sin: What Islam says about sin:
Sin is the violation of God’s perfect and holy standards. All people are sinners (Rom. 3:10, 23) and are under the curse of sin – spiritual and physical death (Gen. 2:17, 3:17-19; Rom. 6:23).  Only faith in Christ and His work on our behalf frees us from sin and its consequences (John 3:16, 5:24; Eph. 2:8-9). Sin is lack of obedience to Allah. Man is sinful by act only, not by nature. Original sin is viewed as a “lapse” by Adam. Man is not really “fallen” in his sin nature; he is merely weak and forgetful. The most serious sin is that of shirk; for example, considering God as triune. Sin is thought of in terms of rejecting right guidance. It can be forgiven through repentance. No atonement is necessary.
What the Bible says about heaven and hell: What Islam says about heaven and hell:
Hell is a place of everlasting conscious existence, where the unbeliever is forever separated from God (Matt. 25:46; Luke 16:19-31; Rev. 14:9-11, 20:10).  As for heaven, all believers have God’s promise of a home in heaven, will go there instantly upon physical death, and will return with Christ from heaven to earth one day (Luke 16:19-31; John 14:1-3; 2 Cor. 5:8; Rev. 19:11-16). Muslims believe in heaven and hell. Allah predetermines the eternal destiny of each person, and the hope of salvation for the Muslim is based on works, although no Muslim has the absolute assurance of heaven. Islam teaches its followers to prepare for the Day of Judgment, in which each person’s good and evil works will be measured, resulting in heaven or hell.
