Psalm 100: Worship Because He Is God
Psalm 100 grounds worship in facts, not feelings: Yahweh alone is God, he made and keeps his people, and his steadfast love and faithfulness never run out. Thanksgiving and praise are how we enter his presence, not a price we pay to get there.
Psalm 100: Serve the Lord With Gladness
Psalm 100 tells us to serve with gladness, but it does not ask us to manufacture the feeling. Gladness grows from knowing whose we are: the God who made us, keeps us, and stays faithful to every generation.
Psalm 100: Enter His Gates With Thanksgiving
Psalm 100 grounds thanksgiving in God's character rather than in the worshiper's mood. The command to enter his gates with thanksgiving rests on the claim that Yahweh made us, keeps us, and is good and faithful to all generations.
