Every mystery of God is trapped in knowledge. And knowing is a function of teaching. The people cannot grow above their knowledge level of the Lord. The problem statement of the church as released by Jehovah is: My people perish for lack of knowledge (Hosea 4:6). And our Lord Jesus speaking sometime later revealed: ‘This is eternal life, that they might know thee the only true God, and Jesus Christ, whom thou hast sent (John 17:3). When we consider this matter closely, we can conclude that both the teacher and his teaching are of great concern in the progress of the pilgrim.
