They say

“Jesus is not the Son of God! God is One; He begets not, nor is He begotten. God cannot have a wife or physical child (Surah 112:3).”

The 30-second answer

Christians firmly agree that God has no physical consort and never fathered a child in a biological sense. "Son of God" is a title of divine nature and eternal relationship.

💡 Ask them back“Did you know the Bible agrees that God never had sexual relations with anyone? In the Bible, 'Son of God' means the eternal Word of God made flesh. Did you know the Quran in Surah 4:171 also calls Isa 'His Word' and 'a spirit from Him'—which is why he is honored with titles like Kalimatullah and Ruhullah? Can God's Word be created, or is God's Word eternal?”
⚠️ What not to sayNever say "God mated with Mary." That is blasphemy in both Christianity and Islam! Clarify what the Bible actually means.

📖 The full defense

Clarify Semitic Idiom:
In Arabic and Hebrew, "son of" frequently denotes character or nature (e.g. ibn al-sabil, "son of the road," means a traveler; a "son of peace" is a peaceful man, Luke 10:6). Jesus is the eternal Word of God (Logos), sharing the very essence and deity of the Father.

The Quran's Own Description:
Surah 4:171 calls Jesus "His Word which He directed to Mary and a spirit from Him." In classical Sunni theology (the Ash'ari and Hanbali schools), the speech of Allah (Kalam Allah) is uncreated and eternal. Muslims usually answer that Jesus is called "a word" because he was created by Allah's command "Be!" (Surah 3:59)—yet of all the prophets, Jesus alone bears this title. The Gospel explains why: He is the eternal Word who became flesh.

Christ's Eternal Nature:
John 1:1 declares: "In the beginning was the Word, and the Word was with God, and the Word was God... and the Word became flesh and dwelt among us."

✝️ Scripture anchors (NKJV)

John 1:1, 14
“In the beginning was the Word, and the Word was with God, and the Word was God... And the Word became flesh and dwelt among us, and we beheld His glory, the glory as of the only begotten of the Father, full of grace and truth.”
Hebrews 1:2-3
“God has in these last days spoken to us by His Son... who being the brightness of His glory and the express image of His person, and upholding all things by the word of His power.”

🔁 If they push back…

The comeback you are most likely to hear next — and a reply that keeps the conversation moving toward Jesus.

They say“Surah 3:59 says Isa is like Adam: Allah created him from dust, said "Be!", and he was. He is called a "word" because he was created by Allah's command, not because he is Allah's eternal speech.”
You can sayThat's the standard answer, and it deserves respect. But Adam, the angels, and the heavens were all created by "Be!"—yet the Quran gives the titles "His Word" and "a spirit from Him" to Jesus alone. The Gospel explains the difference: the Word did not merely come into being by God's command; He was with God in the beginning and then became flesh (John 1:1, 14).
They say“The Bible calls lots of people "sons of God"—Adam (Luke 3:38), Israel (Exodus 4:22), peacemakers (Matthew 5:9). Jesus is a son of God just like them.”
You can sayTrue—the phrase can be used broadly. But Jesus is called the only begotten (monogenēs, "one and only, unique") Son (John 1:18; 3:16). He shared the Father's glory "before the world was" (John 17:5), and when He called God His own Father, His hearers understood He was "making Himself equal with God" (John 5:18). No prophet or peacemaker ever claimed that.
🕊️ Pentecostal key — the Spirit on the streetPray for dreams and visions of Jesus (Isa al-Masih). Many Muslims worldwide testify to encountering Jesus in dreams. Ask the Holy Spirit to reveal Jesus' love to them.
