Imagine two patients diagnosed with terminal cancer.
Both are prescribed chemotherapy. One receives the real thing—an intravenous mixture packed with cytotoxic agents designed to destroy cancer cells. The other receives a solution labeled “chemo,” but it’s made of vitamins, sugar water, and saline. It carries the name, but lacks the necessary power to save. As such, One is healed. The other is not.

Why? Because despite the label, only one contains the active ingredient—the thing that actually kills the cancer.

This is the difference between the Christian God and the god of Islam.

What Makes Chemo Work?

Chemotherapy isn’t just a name—it’s a treatment defined by its active agents. Drugs like cisplatin, doxorubicin, or paclitaxel do the hard work: they attack DNA, disrupt cell division, and force cancer cells into programmed death. BUT, if you strip away those compounds, you no longer have chemotherapy. You have a label without power.

The Same is True of God

Muslims and Christians may both use the word “God,” and they may even believe they are worshiping the one Creator. But when you examine the actual content—the nature and work of that God—you quickly see they are not the same.

Here’s what the Christian God possesses that the Muslim god denies:

1. The Trinity – God is Father, Son, and Holy Spirit. This is not an add-on; it is God’s eternal identity.
2. The Incarnation – God became flesh in Jesus Christ. Islam rejects this completely.
3. The Cross and Resurrection – At the center of Christian faith is the saving death and bodily resurrection of Jesus. Islam denies both.
4. Faith-Based Righteousness – Christianity offers salvation by grace through faith in Christ. Islam teaches salvation by works and merit.
5. The Bible – Christians receive the Old and New Testaments as God’s Word. Muslims reject or overwrite this revelation with the Qur’an.

By the way, even Muslims don’t believe we worship the same God.
The Qur’an explicitly denies the deity of Christ, and Islam considers the worship of Jesus as “shirk”—blasphemous idolatry.
So if Jesus is God to Christians, and not God to Muslims, we are not worshiping the same being.

Why This Matters

To say that Christians and Muslims worship the same God is not just misleading—it’s spiritually dangerous. It may sound respectful, even tolerant, but it subtly denies the heart of the gospel.

If you take away God’s Son, God’s Spirit, God’s Word, and God’s saving grace—you don’t just have “a different perspective on the same God.”
You have a different god altogether.

Jesus said, “No one comes to the Father except through me” (John 14:6). That statement is not just exclusive—it’s definitive. A god who cannot be approached through the Son is not the Father. A worship system that denies the cross is not centered on the true and living God (see Mark 8:29-33).

Conclusion: Chemo by Name Isn’t Enough

If you jumped to the bottom of this article for the answer, here it is: Christians and Muslims do not worship the same God. In fact, any religion that is not Christianity does not worship the same God of Christianity. Real chemo contains real power. Real salvation comes from the real Triune God—Father, Son, and Holy Spirit—who acts in history, speaks through Scripture, and saves by grace. Anything else may carry the name, but it cannot heal the soul.
