These impure ones are at the bidding of their inner fears. In relation to the world they are like a seven stone weakling in the boxing ring with a heavyweight champion. Yes, they may be knowledgeable, confident and eloquent, but they are only so when not in the boxing ring! They avoid confrontation at all costs.
They will speak forever and with great eloquence about what they believe, but not a word will they say of what they reject. They can speak lofty words, but not hard, cold and crooked words. It is more than their life is worth to offend anyone, so they speak in the eternal positive, a bit like smiling at people you hate - to keep the peace. They uplift, but they do not injure and punish. They pinch and poke into action, but do not brandish the stick of Truth. They are revered because they serve the superstitions of the people, or at least, do not dismantle them.
The Man of God is no such beacon of impressive words and pleasant wisdom. He is a solitary Knight of Faith, complete with diamond sword and impregnable armour. He fears nothing. Concepts of positive or negative, pleasant or disturbing, do not occur to him. Nor does he consider recognition, fame, or death. He simply speaks the truth, and in such a way that he does not cloak it with the carnality of finitude. There is no doubt as to what he is saying. It is always clear where he stands. He does not erect false signposts which point elsewhere, or innocently proclaim "Not here".
Silence and half-truths are worse than complete lies: they are deceptive. If truth does not confront untruth directly, then it is not truth. I've had enough of the soft, now give me the hard! Take your charcoal and give me diamond! If you don't confront lies face to face, then you behave as a buffalo with a butcher.
