James 3:13–18 questions our concept of who is wise and understanding. James quickly answers: the truly wise, understanding person is one whose faith in God leads to selfless good works. Wise people live in the humility of wisdom, setting themselves aside to serve others. That’s not worldly wisdom, which leaves each person responsible to serve him- or herself first. Earthly attitudes are driven by envy for what others have, and an ambition to take it. The result is disorder and evil instead of the peace, gentleness, and mercy that follow from living by heaven’s wisdom.
