The sermon centers on the theological significance of God's greeting in worship, emphasizing that it is not a mere formality but a divine, vertical exchange where God speaks first through Scripture, affirming His grace, peace, and covenantal presence to His people. Drawing from the opening salutations of 1 and 2 Peter, it highlights how these words—grace and peace multiplied—are rooted in God's sovereign election, the sanctifying work of the Spirit, and the atoning blood of Christ, offering assurance to both believers and unbelievers. The liturgical structure of worship is defended as intentionally dialogical, with God's word initiating the encounter, ensuring that all elements flow upward in reverence and response, preserving the vertical nature of true worship. This divine greeting, delivered through the ordained minister with raised hands, is likened to a sacred handshake—personal, firm, and life-giving—reminding the congregation that they are known, forgiven, and welcomed by the triune God despite their sin. The sermon calls the congregation to receive this greeting with humility, faith, and attentive hearts, recognizing that it sets the tone for the entire worship service and anchors all subsequent elements in the gospel's truth and mercy.
