A prayer to remain vigilant in all things. Pope reminds himself of his own blindness, his own ignorance, and that happiness can only be found in God's word. It's a religious text with simple meaning and application. The calls for compassion are clear and relevant to people of all walks of life, regardless of religious belief. "Teach me to feel another's woe, to hide the fault I see; That mercy I to others show, That mercy show to me."
While the messages are very much couched in traditional Christian guise and language, I feel that the message, the desires for mutual compassion and understanding, for mercy and wisdom, transcend the religious context.
