"what good is religion?"
[22] But be doers of the word, and not hearers only, deceiving yourselves. [23] For if anyone is a hearer of the word and not a doer, he is like a man who looks intently at his natural face in a mirror. [24] For he looks at himself and goes away and at once forgets what he was like. [25] But the one who looks into the perfect law, the law of liberty, and perseveres, being no hearer who forgets but a doer who acts, he will be blessed in his doing.
[26] If anyone thinks he is religious and does not bridle his tongue but deceives his heart, this person's religion is worthless. [27] Religion that is pure and undefiled before God the Father is this: to visit orphans and widows in their affliction, and to keep oneself unstained from the world.
