I mentioned in Gospel Disproof #32 that your salvation depends on believing what fallible men say about God. A Christian commenter named Eric replied:
Not at all. God has given us His supernaturally preserved Word which has proved to be a trustworthy guide for life and practice through the ages.
He is referring to the books of Moses, the prophets, the apostles, and the evangelists, collectively known as “the Bible” or “the Word of God.” For almost 2,000 years, the writings of these men have led and guided the Church in their role as God’s Word—even though none of the authors is God. If you grew up Christian like I did, it seems perfectly plausible and natural, but if you stop and think about it, it’s really a very peculiar situation. Why would you need to be led by a humanly-authored book about God if you had a real God to guide you?
