What is to fear God? And how to shun evil?

“To fear God” does not mean nameless fright and horror, nor to evade, nor to put at a distance, nor is it idolization or superstition. Rather, it is admiration, esteem, trust, understanding, caring, obedience, consecration, love, as well as unconditional and uncomplaining worship, requital, and surrender. Without genuine knowledge of God, humanity will not have genuine admiration, genuine trust, genuine understanding, genuine caring or obedience, but only dread and unease, only doubt, misunderstanding, evasion, and avoidance; without genuine knowledge of God, humanity will not have genuine consecration and requital; without genuine knowledge of God, humanity will not have genuine worship and surrender, only blind idolization and superstition; without genuine knowledge of God, humanity cannot possibly act in accordance with the way of God, or fear God, or shun evil. Conversely, every activity and behavior in which man engages will be filled with rebellion and defiance, with slanderous imputations and calumnious judgments about Him, and with evil conduct running contrary to the truth and to the true meaning of God’s words. 

 Having real trust in God, humanity will really know how to follow God and depend on Him; only with real trust in and dependence on God can humanity have genuine understanding and comprehension; along with real comprehension of God comes real caring for Him; only with genuine caring for God can humanity have genuine obedience; only with genuine obedience to God can humanity have genuine consecration; only with genuine consecration to God can humanity have requital that is unconditional and without complaint; only with genuine trust and dependence, genuine understanding and caring, genuine obedience, genuine consecration and requital, can humanity truly come to know God’s disposition and essence, and to know the identity of the Creator; only when they have truly come to know the Creator can humanity awaken in themselves genuine worship and surrender; only when they have real worship for and surrender to the Creator will humanity be able truly to put aside their evil ways, that is to say, to shun evil.
