William Law

Whenever a man allows himself to have anxieties, fears, or complaints, he must consider his behavior as either a denial of the wisdom of God or as a confession that he is out of his will. To be always in a thankful state of heart before God is not to be considered a high plane of spirituality but rather the normal attitude of one who believes that “all things work together for good to them that love God, who are called according to his purpose.”
