Corporate worship is not a human initiative but a divine call, rooted in God’s covenant faithfulness and initiated by His sovereign grace. The call to worship, grounded in Scripture and centered on God’s self-revelation, is not a mere formality but the essential moment when God draws His people from the world into His holy presence, renewing the covenant relationship through His spoken word. This act of divine initiation is vital because humanity, dead in sin and prone to spiritual apathy, cannot summon itself to true worship; only God’s steadfast love and faithful presence can awaken and sustain it. The Psalms, especially Psalm 100, exemplify this divine summons, combining vivid commands to worship with profound reasons drawn from God’s identity, creative power, and eternal faithfulness. As believers respond to God’s call, they are transformed, not by their own effort, but by the living and active Word, which accomplishes God’s purpose and draws them into the eternal worship of heaven. Thus, every gathering is a sacred encounter where God speaks, and His people must hear, respond, and worship in spirit and truth.
