David Gullian spent his entire life immersed in Christianity — raised by Baptist missionaries who served for 50 years in the Philippines. Yet his honest investigation of the Bible and the Quran led him to an undeniable conclusion: Islam is the truth. His remarkable journey from a missionary family to embracing Islam is a powerful testimony that when a sincere heart seeks the truth, Allah guides them to it.
A Lifetime in Christianity and the Seeds of Doubt
Even as a young person, David noticed a gap between the “Jesus of faith” as taught in churches and the actual historical person of Jesus. It was not until he began studying Islam that the pieces finally came together. When a Muslim scholar asked him to investigate, David applied the Old Testament’s own criteria for identifying a true prophet to Prophet Muhammad (peace and blessings be upon him) — and to his great surprise, Muhammad fit every criterion perfectly.
“I read both translations of the Quran over a two-week period, and I felt a strong compulsion to become a Muslim. But I did not want to become a Muslim. I told myself: if I can find just one good reason not to, I will not. After three months, I could not find a single reason.” — David Gullian
What Islam Really Teaches
David explains that the core message of Islam is the same message all prophets delivered: make God central to your life, and prove it by taking care of your fellow human beings. This is exactly what Jesus taught in the Gospels — to love God, fear God, and obey God. Islam does not contradict the original teachings of the prophets; it completes and preserves them. Every Friday sermon in every mosque reinforces this same timeless message.
“Islam, if practiced the way it is supposed to be, means peace. It means the best form of life. If a person makes God the center of their life and takes care of their fellow human being, they make the world a better place. That is what Islam is all about.” — David Gullian
Key Takeaways from This Conversion Story
- Prophet Muhammad (peace and blessings be upon him) meets every biblical criterion of a true prophet as defined in the Old Testament
- The Quran confirmed and clarified what the Bible originally taught about the oneness of God and the role of Jesus as a prophet
- Islam and good citizenship are fully compatible — the values of justice, peace, and caring for others are at the heart of both
- Honest investigation of Islam, free from cultural bias, consistently leads sincere seekers to recognize its truth
David Gullian’s story is a reminder that Islam is not defined by ethnicity or culture — it is a universal message for all of humanity. If you are searching for truth, study the Quran with an open heart, examine the life of Prophet Muhammad (peace and blessings be upon him), and let the evidence speak for itself.
