Teaching the word of God

The Bible, the word of God, is a deep, rich, sometimes confusing book. I see some church teaching and teachers that speak about scripture as if they have ALL the answers. Given the fact that the Bible is the word of God and that any teacher or any reader is an imperfect human being, I think some teachers ought to take a more humble approach. I often imagine God up in heaven looking down upon some sincere teachers thinking "that's absurd." Of course my understanding of the Bible is also imperfect and continues to evolve.
