"Fear," said he, "the Lord, and keep his commandments. For if you keep the commandments of God, you will be powerful in every action. Every one of your actions will be incomparable, for fearing the Lord you will do all things well. This is the fear that you ought to have, that you may be saved. But don't fear the devil, for fearing the Lord you will have dominion over the devil, for there is no power in him. (Shepherd of Hermas II:7)

Our books consistently maintain 4-star and better ratings despite the occasional 1- and 2-star ratings from people angry because we have no respect for sacred cows.

Those, who denounce fear, assail the law; and if the law, plainly also God, who gave the law. ... Cautious fear (ευλαβεια) is therefore shown to be reasonable, being the shunning of what harms; from which arises repentance for previous sins. "For the fear of the LORD is the beginning of wisdom; good understanding is to all that do it" [Ps. 111:10]. He calls wisdom a doing, which is the fear of the Lord paving the way for wisdom. But if the law produces fear, the knowledge of the law is the beginning of wisdom; and a man is not wise without law.(Miscellanies II:7)

Since God deemed it advantageous that from the law and the prophets men should receive a preparatory discipline by the Lord, the fear of the Lord was called the beginning of wisdom. It was given by the Lord, through Moses, to the disobedient and hard of heart. For those whom reason will not convince, fear tames. The Instructing Word, seeing this from the beginning, purified by each of these methods and adapted the instrument suitably for piety. (Miscellanies II:8)

This is an ad written by me, Paul Pavao: I get a commission if you buy Xero shoes, which does not increase your cost. Barefoot running/walking is the best thing for your feet--if we did not walk on cement, asphalt, and gravel. Normal shoes compress your toes and do a lot of the work your lower leg muscles should be doing. Xero shoes are minimalist and let your toes spread and your feet do the work they are supposed to do.
