1 Thessalonians 5:22
Abstain from all appearance of evil.
A missionary magazine, in giving an account of the conversion to Christianity of a high-caste Brahmin in India, stated, as a good test of the new convert's sincerity, the following fact: A Christian friend, knowing that the Hindoo custom of wearing the hair long, and fastened with sacred flowers in a knot at the back of the head, was intimately connected with certain acts of idolatrous worship, advised the Brahmin to cut off this hair at once, and thus demonstrate to all men that he had really ceased to be an idolater. To this suggestion the convert promptly replied, "Yes, certainly, for it is the devil's flag." Accordingly, the hair was immediately cut off.
