We (humans) are naturally fearful creatures (e.g. who hasn't been afraid of the dark?) and we tend to make up nonsense about things we don't understand. Once we understand something, i.e. once we understand the truth of something, we have less need to fear it.
Indeed, truth is something we all naturally fear. But once we understand truth, we become fearless, and are then empowered to act boldly. A leader is someone who understands some truth, or a distortion of it, and who feeds people understanding. Once we hear what we can understand of a truth and agree with, we become less fearful of an unknown, and also feel empowered to act boldly.
The danger is that nobody really knows or understands TRUTH the way God does. Even the message revealed to us through Jesus is a distortion of the TRUTH, because we hear it with ears which cannot hear, or see it with eyes which cannot see. We naturally have fear, then, of TRUTH (God), but not the one who reveals it (Jesus)...
Still, while nobody understands TRUTH, we offer ourselves what we think is truth or distort what we hear in order to understand it thereby removing our fear of it...
However, it is impossible to know completely, absolutely, 100 percent of God's TRUTH... therefore, naturally be fearful of it.
