Why Believe in the Trinity?


Many people would say that if you can't explain something, you shouldn't believe it.

Many people would say that if you can't explain something, you shouldn't believe it. Because the Trinity couldn't be explained by human reasoning, I was told Christians believed in a "three-headed-monster god." But just because something can't be explained, doesn't make it impossible to believe in. Try to explain love, beauty or friendship. You can't create these things in a test tube or offer a rational explanation as to why they exist. But they do exist. You know it as well as you know math and grammar facts.

The same is true of the Trinity. Yes, it's mysterious. No, it can't be understood or explained. But that doesn't make it untrue. So what does make it true? The Trinity is true, because it's taught as truth in God's Word—the Bible.

First off, the Bible tells us there is only one God: "You were shown these things so that you might know that the Lord is God; besides him there is no other" (Deuteronomy 4:35). One God—absolutely. But one God who exists in three distinct Persons:

God the Father

When Jesus is praying to the Father, he says: "Now this is eternal life: that they may know you, the only true God" (John 17:3). And in 1 Corinthians 8:6, we are told that there is "but one God, the Father, from whom all things came and for whom we live."

God the Son

In Colossians 2:9, the Apostle Paul makes this powerful statement about Jesus' divinity: "For in Christ all the fullness of the Deity lives in bodily form." And then Titus 2:13 talks about "our great God and Savior, Jesus Christ." And the first chapter of John teaches that when Jesus came to Earth, he was God in human form.

God the Holy Spirit

In Acts 5, we read about someone who told a terrible lie. This guy was confronted with these words: "How is it that Satan has so filled your heart that you have lied to the Holy Spirit … You have not lied to men but to God." And 1 Corinthians 3:16 says Christians are God's temple—the place where God's Spirit lives.

Over the centuries, Christians everywhere have believed in a "God in three Persons." In fact, churches reaffirm this belief when they baptize believers "in the name of the Father and of the Son and of the Holy Spirit" (Matthew 28:19). And great statements proclaiming belief in the Trinity (like the Apostles' Creed and the Nicene Creed) are recited every Sunday morning in churches around the world. Of course, these statements are true because they are based on The Truth—the very Word of God.
