Overview
Understanding Who Is God? The Quran and the Bible Compared
The Quran and the Bible agree that God is the eternal Creator: knowing, merciful, just, and unlike creation. Their decisive disagreement concerns God's nature. Islam teaches absolute oneness and rejects the Trinity and incarnation; mainstream Christianity affirms both. The question is therefore not whether God is worthy of worship, but how God has described Himself and whom He has authorized to receive worship.
notes
The Question We Are Really Asking
The question 'who is God?' Breaks into smaller, concrete questions that both scriptures answer directly. Is God one — and in what sense? What is God like: what are His names and attributes (an 'attribute' is simply a quality God has, such as mercy or knowledge)? Is He primarily merciful, primarily just, or both at once? Can He be seen, imagined, or represented? Does He ever take on a created form? And how does He relate to us — as a distant force, a loving parent, a master, a judge?
A fair comparison has to notice something honest at the outset: Muslims and Christians are not arguing about whether there is one eternal Creator. Both firmly say yes. The real disagreement is about what that one God is like and whether He ever entered His own creation. Keeping that distinction clear prevents the most common caricatures on both sides — that Christians worship three gods (they say they do not), or that Muslims worship some other, foreign deity ('Allah' is simply the Arabic word for God).

history
Where These Texts Come From
The Bible is not a single book but a library written over many centuries. The Hebrew Bible (which Christians call the Old Testament) was composed mainly in Hebrew and contains the passages about God's oneness, eternity, and mercy quoted below; Deuteronomy 6:4, known in Judaism as the Shema, remains the central Jewish declaration of faith recited daily. The New Testament was written in Greek in the first century CE by followers of Jesus.
Christian doctrine about God's inner nature developed over the following centuries. The classic formulation of the Trinity — one God in three co-equal persons: Father, Son, and Holy Spirit — was hammered out in church councils, beginning with the Council of Nicaea in 325 CE and continuing through later fourth-century councils. Christians regard this doctrine as the correct interpretation of their scriptures, not an addition to them; that is how their own scholarship describes it, and a fair reader should know that.
The Quran was proclaimed by the Prophet Muhammad in seventh-century Arabia over roughly two decades. It presents itself not as a new religion's founding document but as a restoration of the original message of all prophets — Abraham, Moses, and Jesus included — centered on the absolute oneness of God, called Tawhid in Arabic. Strikingly, the Quran speaks directly to Jews and Christians ('People of the Book'), affirming that their God and its God are the same, while correcting what it presents as later misunderstandings about His nature.

God in the Quran
Surah Al-Ikhlas gives the Quran's shortest complete answer: God is one, self-sufficient, neither begetting nor begotten, and without equal (Quran 112:1-4). These statements exclude ancestry, offspring, incarnation, and every division of divinity.
Quran 59:22-24 adds names that show whom Muslims worship: the Knower of the seen and unseen, the Most Compassionate, the Most Merciful, the Sovereign, the Holy, the Guardian, the Almighty, the Creator, and the Fashioner. Quran 6:103 states that vision cannot encompass Him, while Quran 7:180 directs believers to call upon Him by His beautiful names.
This is not a distant or impersonal God. He knows, creates, forgives, judges, guides, and responds. His nearness does not require Him to enter creation, and His mercy does not require another divine person to mediate it. Islam holds transcendence and nearness together without blurring Creator and creation.

God in the Bible
The Bible also contains powerful declarations of one eternal Creator. God identifies Himself to Moses in Exodus 3:14; Deuteronomy 6:4 declares that the Lord is one; Psalm 90:2 calls Him God from everlasting to everlasting; Isaiah 40:28 names Him the everlasting Creator; and John 4:24 says that God is spirit. Exodus 34:6-7 joins mercy, patience, justice, and forgiveness.
Mainstream Christianity reads these texts together with passages about the Father, Son, and Holy Spirit and concludes that the one divine being exists in three persons. It also teaches that the Son became human in Jesus. Christians therefore regard the Trinity and incarnation as developments that preserve monotheism rather than abandon it.
Islam honors the Bible's clear descriptions of God's unity and attributes while questioning that later theological step. The issue is not whether Christians intend to worship one God; they do. The issue is whether Jesus and the prophets explicitly taught that God's one being contains three co-equal persons.

Side by Side: Agreement and Difference
The shared foundation is substantial: God is eternal, knowing, powerful, merciful, just, and worthy of complete worship. Neither tradition permits idols or treats the universe as self-created.
The decisive difference is how divine oneness is defined. Christianity says one being and three persons; Islam says God's oneness is without internal persons, incarnation, or shared worship. Christians appeal to progressive revelation and a combined reading of New Testament passages. Muslims answer that the clearest statements of Moses and Jesus identify one God and direct worship to Him without a tri-personal formula.
The comparison should therefore be tested at its strongest point: which account best matches the prophets' explicit language, preserves God's incomparability, and directs worship without ambiguity? Islam's answer is tawhid—one Creator, one object of prayer, and no partner.

Common Misconceptions
"Muslims worship a different God." Arabic-speaking Christians also use the word Allah for God. The dispute concerns God's nature, not the identity of the Creator of Abraham.
"Christians knowingly worship three gods." Mainstream Christianity rejects three gods and defines the Trinity as one divine being. The Islamic critique addresses that real doctrine rather than a caricature.
"A God without incarnation cannot be loving or near." The Quran joins God's incomparability with direct mercy, guidance, forgiveness, and response to prayer. Nearness does not require embodiment.
"Shared attributes make the doctrines equivalent." Agreement that God is merciful and powerful does not settle whether He is triune or whether worship may be directed to Jesus.

The Islamic Conclusion
Islam calls people to the God proclaimed by the prophets: the one eternal Creator who hears prayer, forgives repentance, and has no equal. It honors Jesus as Messiah without making him the God he worshiped.
Tawhid is not merely the simpler formula. It keeps every divine name, every act of worship, and every hope of forgiveness directed to God alone. That is why the Quran's account of God stands at the center of the Islamic invitation.

Frequently Asked Questions
Q: Do Muslims and Christians worship the same God?
A: Both communities intend to worship the God of Abraham — one eternal Creator. The word 'Allah' is simply Arabic for God and is used by Arabic-speaking Christians too. The disagreement is over God's nature (Trinity and incarnation versus absolute oneness), not over which Creator is meant.
Q: Does the Bible ever call God 'one' the way the Quran does?
A: Yes. Deuteronomy 6:4 — 'Hear, Israel: Yahweh is our God. Yahweh is one.' — is the central creed of the Hebrew Bible. The Quran's Surah Al-Ikhlaas makes the same declaration with added precision: no begetting, no being begotten, no equivalent.
Q: Is the God of the Quran merciful, or mainly a judge?
A: The Quran's most frequent divine names are 'the Entirely Merciful, the Especially Merciful' (Quran 59:22), recited before nearly every daily act. Justice is equally real, but Islamic teaching, like Exodus 34:6-7, places mercy first.
Q: Why does Islam reject calling God 'Father'?
A: The Quran avoids parent-child language for God because, in its view, such language historically slid into literal sonship and division within God. It states that God 'neither begets nor is born' (Quran 112:3). God's tenderness is expressed through names like the Entirely Merciful and the Subtle, the Acquainted.
Q: Can anyone see God, according to these scriptures?
A: The Quran says 'Vision perceives Him not, but He perceives [all] vision' (Quran 6:103) — God cannot be seen in this life. The Bible teaches that 'God is spirit' (John 4:24), while mainstream Christianity holds that God made Himself visible in Jesus — a key point of difference between the two faiths.
Q: Is 'Allah' a name only Muslims use?
A: No. 'Allah' is the standard Arabic word for God, related to the Hebrew Elohim. Arabic-speaking Jews and Christians used it before Islam and still use it today in their Bibles, prayers, and churches.
