The Bible is the foundational Word of God, but are we actually teaching it to people or are we just teaching them about it? Are we leading them in a process of learning to hear from God as they read His Word, or are we just teaching them knowledge about the Bible?  If we are, where is our proof?  If we cannot point to where we can see evidence of them applying the word of God in their lives and being changed, then maybe we need to reevaluate how we are teaching the Bible.
