 You Christians love God, and you love each other, so you sometimes have dinner together. Those lying teachers come to those dinners. But they only come to eat and drink. They dont respect God, and they dont care about people. They only think about themselves. They are really dangerous. You know about rocks in the sea. You know that boats have to keep away from them, or they will wreck the boats. That mob are like those rocks to you. Keep away from them, or they will wreck you. They are useless. They are like clouds that dont have any rain. Those clouds are useless, and the wind just moves them along. Those lying teachers never do anything good. They are like trees that dont have fruit, even when it is the right time for fruit. Those trees are properly useless, so people pull them out of the ground.
