Is the Bible Self-Authenticating?

What does it mean to say that the Bible is "self-authenticating"? If something is self-authenticating, that means that you don't need anything else to authenticate it or show that it real. In terms of the Bible, if it is self-authenticating, that means that the Bible itself shows that it really is the Word of God. However, some who say that the Bible is self-authenticating use that idea to imply that doing apologetics is wrong or unbiblical, that we shouldn't need to give evidence to support the Bible's truthfulness. But is that really what the Bible being self-authenticating means?
