5 More Reasons Why I Trust the Bible

Some time ago I wrote a post called “Why I Trust the Bible.” In that article, I gave five reasons why I personally believe the Bible to be trustworthy.

There are, of course, many more reasons than that to believe the Bible is true, so I thought it would be a good idea to share five more reasons why we can trust the Bible.

We have confidence in the Bible as God’s true and trusted speech to us because:

1. The Bible’s primary author can be trusted.

The Bible was written by many authors over more than two thousand years, and yet it has a unity to it that is unlike any other religious collection of books. This unity exists because one divine author wrote it—God. The Old Testament anticipates the New Testament, and the New Testament recasts old metaphors and imagery, showing forth the organic unity of it all!

As the early church pastor Saint Augustine expressed it, “The new is in the old concealed; the old is in the new revealed.” What this means is that the Bible reads from promise (Old Testament) to fulfillment (New Testament). It moves forward, and when we read ahead, we are told to remember and look backward at what happened long ago in history.

Like any good story, the Bible has characters, plots, subplots, and different settings—yet this one, unified story is the greatest story that was ever told. It’s the greatest story ever told because not only are we told about the meaning of life, but in it, we are given the greatest Savior to behold—one who has come to save us from even death itself and has promised a new world without pain or tears! God has proved himself to be trustworthy in the words and works of Jesus.

2. The Bible is authorized by Jesus.

Because Jesus is God, if he says that he trusts something, then we have good reason to trust it too. We are clay in the hands of the potter, creatures in the hands of the Creator. When Jesus lived on this earth in the first century, he believed that the Old Testament Scriptures were authoritative (Matt. 19:4-5).

Jesus also affirmed that every prophecy in the Old Testament was being fulfilled in himself, as he taught two disciples on the road to Emmaus (Luke 4:21), and before he ascended into heaven, Jesus also authorized his apostles to speak in his name (Matt. 18:18; 28:16-20; Romans 3:2).

This means that they had authority from God to write the rest of the New Testament, so we can trust that the Bible is God’s Word because God himself gave it to us and put his stamp of approval on it.

3. The Bible is without error.

If ultimately God wrote the entire Bible through prophets and apostles (Jeremiah 1:9), cannot lie (Hebrews 6:18), and is the source of all good, then it follows that the Bible is without error, falsehood, or deceit.

“The sum of your word is truth, and every one of your righteous rules endures forever.” (Ps. 119:160)

If this book were full of critical errors, there would, of course, be no point in reading it, but the Bible has more credibility as an historical document.

4. The Bible is clear in its primary message.

The reformer John Calvin observed that Moses was not an astronomer, and the Bible is not a science textbook. If we go to the Bible looking for answers to questions that it never asks, we will surely misunderstand the book. As Jesus said to the Pharisees:

“You search the Scriptures because you think that in them you have eternal life; and it is they that bear witness about me, yet you refuse to come to me that you may have life.” (John 5:39-40)

The basic plotline, God saving a people for himself, runs throughout the whole Bible. This basic message is simple and clearly explained over and over again.

5. The Bible is enough.

The main character and center of the Bible’s plotline is Jesus Christ. Jesus is the climax of the greatest story ever told!

“Then he said to them, “These are my words that I spoke to you while I was still with you, that everything written about me in the Law of Moses and the Prophets and the Psalms must be fulfilled.” (Luke 24:44)

To believe in and to behold this Jesus of the Scriptures is the point of the whole story.

“but these are written so that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name.” (John 20:31)

In the Bible, we learn enough about ourselves to know that we need Jesus as our Savior. In the Bible, we learn enough about a world that is sin-cursed to know that Jesus is bringing us a new world. In the Bible, we have enough to know who God is, what he has done, what he is going to do, and that he forgives and loves us right now.

The Bible is sufficient: we can trust it because the God who wrote it is trustworthy. We can trust him.
