God looks not at the elegancy of your prayers, to see how neat they are; nor yet at the geometry of your prayers, to see how long they are; nor yet at the arithmetic of your prayers, to see how many they are; nor yet at the music of your prayers, nor yet at the sweetness of your voice, nor yet at the logic of your prayers; but at the sincerity of your prayers, how hearty they are. There is no prayer acknowledged, approved, accepted, recorded, or rewarded by God, but that wherein the heart is sincerely and wholly.
Thomas Brooks
