What is there to find fault with in the framing of the body? Come forth into the midst and speak. Control thine own will, and nothing evil shall proceed from any of thy members. For every one of these has of necessity been made for our use. Chasten thy reasoning unto piety, submit to God’s commandments, and none of these members sin in working and serving in the uses for which they were made. If thou be not willing, the eye sees not amiss, the, ear hears nothing which it ought not, the hand is not stretched out for wicked greed, the foot walketh not towards injustice, thou hast no strange loves, committest no fornication, covetest not thy neighbor’s wife. Drive out wicked thoughts from thine heart, be as God made thee, and thou wilt rather give thanks to thy Creator.
