Long before Muhammad was born, Arabic Christians already were referring to God as Allah—and millions continue to do so today. The Allah of Islam, however, is definitely not the God of the Bible. For while Muslims passionately defend the unity of God, they patently deny His triunity. Thus, they recoil at the notion of God as Father, reject the unique deity of Jesus Christ the Son, and renounce the divine identity of the Holy Spirit. Hank Hanegraaff, the host of the 𝘉𝘪𝘣𝘭𝘦 𝘈𝘯𝘴𝘸𝘦𝘳 𝘔𝘢𝘯 broadcast and the 𝘏𝘢𝘯𝘬 𝘜𝘯𝘱𝘭𝘶𝘨𝘨𝘦𝘥 podcast, notes while the Master taught His disciples to pray, “Our Father in heaven,” devotees of Muhammad find the very notion offensive. To their way of thinking, calling God “Father” and Jesus Christ “Son” suggests sexual procreation. The Bible, however, does not use the term begotten with respect to the Father and the Son in the sense of sexual reproduction but rather in the sense of special relationship. Muslims dogmatically denounce the Christian declaration of Christ’s unique deity as the unforgivable sin of shirk. While Muslims readily affirm the sinlessness of Christ, they adamantly deny His sacrifice upon the cross and subsequent resurrection. In addition to rejecting the divinity of Jesus, Islam also renounces the divine identity of the Holy Spirit. Far from being the third Person of the Triune God who inspired the text of the Bible, Islam teaches that the Holy Spirit is the archangel Gabriel who dictated the Qur’an to Muhammad over a period of twenty-three years. Biblically, the Holy Spirit is neither an angel nor a mere mortal; rather, He is the very God who redeems us from our sins and will one day resurrect us to life eternal (Acts 5: 3–4; Romans 8:11).
