Satan is methodical and predictable. If Satan can’t convince you there is no God, or lead you to a false god, he will then try to convince you the Holy Bible is not God’s Word. Be ready for that challenge when the unbeliever throws that back at you. Respectfully disagree and ask the unbeliever to sit down and go over the proofs I sent you that the Bible is indeed the unerring word of God. Ask them what do they have to lose? Tell them they have nothing to lose and everything to gain if you’re right.
If Satan can’t refute the Bible is God’s Word he will try to convince you the Bible contains so many errors it’s impossible to know what God really says. That is not true. Bible scholars agree the Bible is 99.9% accurate. No ancient writing has been so meticulously translated and copied as the Bible. There are many thousands of copies of ancient Scripture, many from the first century or earlier, that consistently present God’s Word. The few errors found were very minor mistakes that did not affect any church doctrine of faith.
If unbelievers tell you the Bible contains errors refute that argument. Ask them to show you or tell you what the errors are. They can’t do it because there aren’t any and they are just repeating talking points they heard from somebody else. For 2000 years critics have been trying to discredit the Bible to no avail. The Bible has withstood ever analysis and every test thrown at it. The authenticity of the Bible is well documented so we can safely say the Bible is God’s revelation to man.
