This question goes deep—into history, culture, and the core of human longing. It’s not just about theology. It’s about identity, purpose, and the nature of reality itself.
So why do Christians hold, often gently but firmly, to the belief that there is only one true God?
Let’s take a look.
A Radical Beginning
Christianity did not invent the idea of one God. It inherited it.
Long before Jesus walked the earth, the Hebrew people—descendants of Abraham—held to a stunning, unpopular claim:
“Hear, O Israel: The Lord our God, the Lord is One.”(Deuteronomy 6:4)
This was radical in a world full of gods and idols, where every river, tree, or mountain had its own spirit. But the God of Israel wasn’t one among many. He claimed to be the source of all things, the Creator, and the Only One.
Not a Power Struggle, but a Love Story
The Christian view of one God isn’t about domination or exclusivity—it’s about truth and relationship. Christians believe that if God is real, He must be more than a regional force or a cultural construct. He must be the origin of life, the foundation of love, the reason anything exists at all. And that means there can’t be many equal, competing gods. There can only be One—the eternal source behind the universe itself.
But this One God is not distant or cold. Christians believe He is personal, relational, and deeply involved with His creation. But just like the people of ancient past who taught Israel that God is One: this originated because some people claimed to have met Him, walked with Him, and knew Him. And they wrote about it, sang about it, and taught it to their children. Why are there people that claim to know Him? How is this possible? Not everything in this world can be explained, but it is worthy taking note of. These people were backed with supernatural encounters that both thrilled and terrified others. For example, a man who made a sea rise and part helping hundreds of witnesses escape. These stories and even modern day accounts are explored further later.
Revealed Through Jesus
Christians believe the one true God revealed Himself fully through a real person: Jesus of Nazareth. In Jesus, Christians see more than a messenger. They see the visible image of the invisible God—a God who walked among us, full of compassion, healing, and truth.
He didn’t just talk about God. He claimed to be one with Him and gave others power to feel that promise.
“Anyone who has seen Me has seen the Father.” (John 14:9)“I and the Father are one.” (John 10:30)
These are not small claims. They’re either blasphemy—or truth so deep it shakes the world.
More Than Philosophy
This belief in one true God isn’t built on nice ideas. It’s built on history, experience, and what Christians describe as encounter.
It’s the consistency of the biblical narrative across thousands of years.
It’s the witness of lives transformed by the love of God.
It’s the awe of a Creator who speaks in both Scripture and starlight.
It’s the experience of answered prayers, deep peace, and unexpected encounters.
Christians don’t believe in one God because it’s convenient. They believe it because they have felt Him, and everything else has fallen short.
Why Not Many Paths?
It’s often said that all religions lead to the same God.
But Christians believe that truth matters—not to exclude, but to set people free.
There are many gods and idols in the world. But, Christians believe they lead to empty destinations. And they believe that while they may be paths promising to be true with supernatural occurrences, they will not bring eternal life when destruction comes. Biblical prophecy is one of the most haunting and accurate to-date of any written works known to mankind. And it warns of an event in the future to come. This is a different topic for a different chapter, however.
If Jesus truly rose from the dead...If He truly was God in human form...Then He is not just one path among many. He is the bridge built by God Himself.
“I am the Way, the Truth, and the Life,” Jesus said. “No one comes to the Father except through Me.” (John 14:6)
Not out of arrogance. But out of intimacy.
Christians believe God made the way—and invites all to walk it.
A Final Thought
If there is only one true God, and He truly made us...Then to know Him is not a restriction.
It’s a homecoming. Christians believe that in a world of many voices, many idols, and many gods... There is One who created us, one who loves us, and one who can lead us back to peace. Maybe that's worth exploring.
