"The only way your powers can become great is by exerting them outside the circle of your own narrow, special, selfish interests. And that is the reason of Christianity. Christ came into the world to save others, not to save himself; and no man is a true Christian who does not think constantly of how he can lift his brother, how he can assist his friend, how he can enlighten mankind, how he can make virtue the rule of conduct in the circle in which he lives."
