Endurance is not the same thing as patience. We may endure with angry or bitter spirits. James call us to patience which blossoms into faithfulness.
Faith That Works: James has been called the New Testament Book of Proverbs. It is a book of wisdom for Christians - wisdom that is evident in our conduct. We are reminded that wisdom is more than just what we know. Wisdom shines through our speech, works, humility, prayers and patience through troubles. So for those who need wisdom - God has an endless supply to give.
