To help you prove whether the Bible is true and trustworthy, read our free study aid Is the Bible True? Many other published books are also very helpful.
Some of the major proofs of the Bible's divine inspiration are:
Many past events were prophesied in the Bible and came to pass exactly as foretold. It will be even more impressive to see future prophesied events happen exactly as promised. For more information, read the Bible study aid You Can Understand Bible Prophecy.
The Bible never contradicts itself! This is truly miraculous considering that it was written over the course of some 1,500 years by about 40 different authors! Some details in the Bible may seem to contradict at first glance, and many skeptics point to apparent discrepancies to try to disprove divine inspiration. However, several good books have been written that explain such alleged discrepancies, showing that when properly understood they are not contradictory. If there are a few that we can't readily explain, they merely show our human lack of understanding, not errors in the Bible.
There is no conflict between true science and the Bible. (Evolution is a theory for explaining certain observations in science, not science itself.) When science and the Bible seem to conflict, one or the other is not being correctly understood. The Creator God who inspired the Bible understands science better than all scientists put together.
This is the study of the material remains of past people's lives and activities. Many biblical sites have been found, and the amount of evidence confirming the biblical record is enormous. No archaeological discovery to date contradicts the Bible (though some mistakenly interpret some findings as doing so).
Promises and prayers
God gives us many promises in His Word. Seeing promises fulfilled is evidence of God's faithfulness. And God promises to answer prayers of His people, especially prayers that are in harmony with His will and promises. Answered prayer can strengthen one's faith in God and His Word more than anything else.
The Bible works!
God's ways work. The Bible teaches countless practical principles for daily life. Just as nature teaches us about invisible physical laws, the Bible teaches that there are also invisible but absolute spiritual laws governing every aspect of human life. The better we understand all those laws and get in harmony with them, the healthier, happier and more successful we will be. God's ways work, and they work wonderfully!
