You cannot go by the judgment of men or by a numerical ballot [to know what is the right religion]. You must go to God himself to find out what is really acceptable. And God tells us here in this text that the religion which God accepts is this: to look after orphans and widows in their distress and to keep oneself from being polluted by the world. That means that religion that is acceptable to God must contain these two features. It must express itself in a love for God and Christ, which manifests itself in service to others, and it must manifest itself in a genuine concern for personal sanctification.1
G. I. Williamson
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.
