Put simply, the doctrine of inerrancy is the belief that the Bible is true.

Of course, there is much more to say about the definition than this. Countless books have been written explaining, defining, and defending this doctrine, not to mention the affirmations and denials of the 1978 Chicago Statement on Biblical Inerrancy. But the gist of inerrancy is the belief that the Bible is God’s Word and that when God speaks, He speaks truth. Thus, belief in inerrancy is the conviction that whatever the Bible affirms is accurate, reliable, and trustworthy.
