My opinion, many 'famous' evangelists, their intentions in the beginning were honourable, sincere. They worked hard, diligent, honest. But somehow they come off the rails, they err, spirituality did not protect them, and they fell. They fell because all religion is flawed. Christian beliefs the bible is from God is their flaw.
External Evidence that the Bible is God’s Word There are also external evidences that indicate the Bible is truly the Word of God. One is the historicity of the Bible. Because the Bible details historical events, its accuracy is subject to verification like any other historical document. Through archaeological evidence and extrabiblical writings, the historical accounts of the Bible proved time and again to be accurate and true. In fact, all the archaeological and manuscript evidence supporting the Bible makes it the best-documented book from the ancient world. That the Bible accurately records historically verifiable events helps substantiate its claim to be the very Word of God and supports trust concerning other matters the Bible addresses. Another external evidence that the Bible is truly God’s Word is the integrity of its human authors. In studying the lives of the authors of Scripture, we find them to be honest and sincere. The fact that they were willing to die often excruciating deaths for what they believed testifies that these men truly believed God had spoken to them. The men who wrote the New Testament and many hundreds of other believers (1 Corinthians 15:6) knew the truth of their message because they had spent time with Jesus Christ after He had risen from the dead. Seeing the risen Christ had a tremendous impact on them. They went from hiding in fear to being willing to die for the message God had revealed to them. Their lives and deaths testify to the fact that the Bible truly is God’s Word. Another external evidence that the Bible is truly God’s Word is the indestructibility of the Bible. The Bible has suffered more vicious attacks and attempts to destroy it than any other book in history. From early Roman Emperors like Diocletian, through communist dictators and on to modern-day atheists, the Bible has withstood a constant onslaught from detractors. Yet it endures and is still today the most widely published book in the world. Throughout history, skeptics have regarded the Bible as mythological, but archaeology has confirmed it as historical. Opponents have attacked its teaching as primitive and outdated, but its moral and legal concepts have had a positive influence on societies throughout the world. It continues to be attacked by pseudo-science, psychology, and political movements, yet it remains just as true and relevant today as it was when it was first written. This should not surprise us. After all, Jesus said, “Heaven and earth will pass away, but my words will never pass away” (Mark 13:31). The Bible, unique among books, has transformed countless lives and swayed whole cultures. After looking at the evidence, one can say without a doubt that God has spoken and that, yes, the Bible is truly God’s Word. https://www.gotquestions.org/Bible-God-Word.html

Some more reasons to believe the Bible: https://www.josh.org/can-really-kno...1tjbhsDXfBaNisT1VylUCXNSRmJFLU-xoC8kQQAvD_BwE Every human being exercises some sort of faith—that the chair will hold them when they sit down, that their spouse will honor their marriage vows, and that their worldview is correct. We need to explore what kind of faith they (and we) have: Unreasonable faith—believing in something in spite of the evidence. Blind faith—believing in something without any evidence. Reasonable faith—believing in something because of the evidence. I want to show evidence that makes it reasonable to believe in the Bible. Empirical evidence— The bibliographical test: determining whether the text of the historical record has been transmitted accurately. Josh McDowell states, “No other work in all literature has been so carefully and accurately copied as the Old Testament.” He can make this claim because the profession of “scribe” was one of the most professional and exacting of all professions. The rigorous standards employed to prove the accuracy of a copy of a biblical manuscript was higher than for any other literature. Most of our modern-day Bibles are based on a 1000-year-old manuscript. But after the Dead Sea scrolls were discovered, we found biblical manuscripts going back to 250 B.C. that confirmed the accuracy of the manuscripts we already had. This led Dr. Peter Flint to conclude: “The biblical Dead Sea Scrolls are up to 1,250 years older than the traditional Hebrew Bible, the Masoretic text. We have been using a one-thousand-year-old manuscript to make our Bibles. We’ve now got scrolls going back to 250 BC. … Our conclusion is simply this—the scrolls confirm the accuracy of the biblical text by 99 percent.” Then regarding the New Testament, Josh McDowell says, “I believe there is more evidence for the reliability of the New Testament than for any other ten pieces of classical literature put together.” Check out this chart reproduced from McDowell’s book God-Breathed to see by comparison to other literature, how close in dating the earliest biblical manuscripts are, and how many of those manuscripts have been discovered! 2. The external evidence test: determining whether the historical record has been verified or affirmed by data outside of itself. Over one-fourth of the Bible is prophetic, and two-thirds of its prophesies have already been fulfilled. For example, 700 years before His birth, the city in which Jesus was to be born was identified by a man named Micah. Time and time again archeologists discover articles that verify the claims in the Bible. This led archeologist Nelson Glueck to conclude, “It may be stated categorically that no archeological discovery has ever controverted a single biblical reference. Scores of archeological findings have been made which confirm in clear outline or in exact detail historical statements in the Bible.” 3. The internal evidence test: determining how of the historical record stands up to the test of internal validity. The Bible was written by 45 different authors, over a span of 1500 years, on 3 different continents, and in 3 different languages. Yet there are no contradictions! Anecdotal evidence— Changed lives. My life is one that has been amazingly impacted by the God of the Bible, as was a man named Saul, who had a total about-face after encountering Jesus. As a result, Christianity was spread far and fast through his writings and world travels. 2. Changed societies. Wherever the Christian faith of the Bible has been put into practice, societies improve. Leonard Sweet notes— “Before Christianity, there were cults that practiced all sorts of human sacrifice as well as self-mutilation and self-castration. Before Christianity, the weak were despised, the poor maligned, the handicapped abandoned. Before Christianity, infanticide was rampant, slavery run-of-the-mill, and gladiatorial combat a form of entertainment. In Jesus’ day, Corinth was famous for its temple prostitutes, continuing a long-standing tradition symbolized by the Corinthian athlete Xenophon.… Aristotle…not only condoned institutionalized slavery but provided an elaborate argument in favor of it. As if that weren’t enough, Aristotle called man ‘begotten’ and woman ‘misbegotten,’ and because a woman’s reasoning was ‘without authority’ accepted no female students. “Only Jesus and His followers known as the church insisted on the concept of human dignity and the value of every human soul. Only the church built hospitals and took care of the abandoned and disabled. Only the church celebrated charity and selflessness as the highest virtue and elevated the status of women.”
Short and to the point: Time and time again archeologists discover articles that verify the claims in the Bible. This led archeologist Nelson Glueck to conclude, “It may be stated categorically that no archeological discovery has ever controverted a single biblical reference. Scores of archeological findings have been made which confirm in clear outline or in exact detail historical statements in the Bible.” https://www.josh.org/can-really-kno...1tjbhsDXfBaNisT1VylUCXNSRmJFLU-xoC8kQQAvD_BwE
Its been proven, the bible has been incorrect numerous times on past events time scale and even that those events occured.
