FAQ: How Do We Know the Bible Is True?

“All Scripture is inspired by God and is useful to teach us what is true and to make us realize what is wrong in our lives. It corrects us when we are wrong and teaches us to do what is right. God uses it to prepare and equip his people to do every good work.” (2 Timothy 3:16–17 nlt)

Over the next few days, we’re going to address some frequently asked questions about the Christian faith. It’s likely that none of these questions will be new to you. You’ve probably heard them—or maybe even asked them yourself—more than once. I want to emphasize that these questions are valid. They often indicate a thoughtful approach to the Christian faith.

But sometimes questions are nothing more than a smokescreen—a way of deflecting the truth of the gospel. They are excuses for not making a decision for Christ. With that in mind, let’s proceed.

In Isaiah 1:18, God says, “Come now, and let us reason together” (nkjv). Christianity is a logical faith. It was only after I became a Christian that the world began to make sense to me. Prior to becoming a believer, I thought that mankind was basically good. And I really struggled with the horrible things that people did to people. But after I became a believer and discovered that the Bible teaches that mankind is sinful, I began to understand. I also discovered that God can change the human heart.

Becoming a Christian doesn’t mean you have to check your brain at the door. Bring your questions, even the tough ones. Find out what God says in His Word. Of course, if we’re going to search for answers in God’s Word, we need to be able to trust it. So, our first question is: How do we know the Bible is true?

We can point to its amazing origin. The Bible is actually sixty-six different books written over a span of 1,500 years by some forty different authors from every walk of life, including kings, peasants, philosophers, fishermen, poets, statesmen, and scholars. Yet every one of them wrote about the same theme, God’s redemption of mankind. Because God Himself directed their words.

We can point to archaeology. For many years, scholars used archaeology to argue that the Bible was unreliable. They could find no evidence of certain names, places, and events mentioned in Scripture. As archaeologists uncover more and more of the ancient world, however, they are discovering that the Bible is quite accurate.

We can point to prophecy, specifically prophecies about the Messiah. Jesus fulfilled many Old Testament prophecies—including being born of a virgin, being born in Bethlehem, and being crucified—centuries after the prophecies were made.

Perhaps most importantly, we can point to what the Bible says about how to know God and how to live in these troubled, crazy times. It’s the only book that speaks with authority in this realm. And it’s the only book whose promises resonate deep within us. Ultimately, the best way to discover that the Bible is true is to experience its truths in your own life.

Reflection question: How have you experienced the Bible truths in your own life?
