The following is from the message The Privy Key Of Heaven by Thomas Brooks. Preached in 1665
Prayers which are not directed to the glory of God . . .
never reach the ear of God, nor delight the heart of God.
The end must be as noble as the means, or else a man may be undone after all his doings. A man's most splendid actions will at last be found to be but splendid sins, if he has made himself, and not the glory of God, the end of those actions.
