Today is Reign of Christ Sunday, also known as Christ the King Sunday. It is an affirmation that Christ and not our national interest, personal self-interest, or political leaders is to be our ultimate concern. Psalm 100 teaches us how and why to worship God as our King. Psalm 100 celebrates God’s loving presence. We are God’s beloved sheep, protected and nurtured by the good shepherd. Thanksgiving and praise are the only responses to divine providence and care. We can live joyfully because love rules the sun, stars, and humankind.
