In Psalm 100, we have an invitation to come into God’s presence and serve him with gladness. We do this because of his good character and his care for us, his people, in so many ways. The returned exiles might not have always felt that joy in worship and we might struggle at times too. They were looking forward and we look back on God’s greatest expression of his steadfast love – sending the Good Shepherd, Jesus. We reflect on God’s Word to “Know the Lord” and be reminded of his goodness, which shapes our lives of service.
