"Shun profane and vain babblings... but foolish and unlearned questions avoid, knowing that they do gender strifes." 2 Tim. 2:16, 23. We need to guard against anything that would tread down the pastures, or foul the waters, by unspiritual and unprofitable discussions, thus depriving the sheep of the flock of the rich and healthful nourishment provided (see Ezek. 34:18,19).
