Relevant Words of God:
Those who do not understand the truth always follow others: If people say that this is the work of the Holy Spirit, then you, too, say it is the work of the Holy Spirit; if people say it is the work of an evil spirit, then you, too, become doubtful, or also say it is the work of an evil spirit. You always parrot the words of others, and are incapable of distinguishing anything by yourself, nor are you able to think for yourself. This is someone without a position, who is unable to differentiate—such a person is a worthless wretch! You always repeat the words of others: Today it is said that this is the work of the Holy Spirit, but chances are one day someone will say it isn’t the work of the Holy Spirit, and nothing but the deeds of man—yet you can’t discern this, and when you witness it said by others, you say the same thing. It is actually the work of the Holy Spirit, but you say it is the work of man; have you not become one of those who blaspheme against the work of the Holy Spirit? In this, have you not opposed God because you cannot differentiate? Who knows, maybe one day some nitwit will appear who says that “this is the work of an evil spirit,” and when you hear these words you’ll be at a loss, and once again bound up by the words of others. Every time someone stirs up disturbance you’re incapable of standing by your position, and this is all because you do not possess the truth.
