Is the Bible truth?
Yes. But it is a big mistake to measure this by using human indicators. For centuries, Christians have agreed on the fact that the Bible is the truth and the Word of God. Disagreements were only about interpretations of it. About a century and a half ago, historical and scientific research began to challenge the truths of the Bible, and Christians responded in different ways. Some tried to prove that the Bible is the Word of God by rejecting the new information they though was in contrast with the Bible. Many Christians still do this. This kind of thinking leads us to adopt the following way of thinking: In order to be the Word of God, the Bible needs to be in accordance with our reason and our understanding of science. Trying to do this, takes a lot of our energy from doing more important things.
The truth and godliness of the Bible is not based on human thinking or science. The truth of the Bible is based on the fact that God has declared Himself and His Will to us in written form. It is a question of faith, which in itself is a gift from God.
For some reason, people on the market square of Thessalonica recognized the call of God in the speech of Apostoles. Paul understands this as work of God:
And we also thank God constantly for this, that when you received the word of God, which you heard from us, you accepted it not as the word of men but as what it really is, the word of God, which is at work in you believers.
(1 Thessalonians 2:13 ESV)
