The doctrine of the Trinity is one of the deepest mysteries of the Christian faith—and that’s a good thing. If God were small enough for us to fully comprehend, he would not be worthy of our worship. In this sermon, we explore how Scripture reveals one God in three persons: Father, Son, and Holy Spirit. Rather than relying on inadequate analogies that often drift into theological error, we turn to the imagery Scripture itself provides. The Trinity is, in some ways, like a family: one nature, distinct persons. Just as a human family shares one human nature while consisting of multiple persons, God is one in essence (“what” God is) and three in person (“who” God is).
From eternity, the Father, Son, and Holy Spirit have existed in perfect communion, sharing an eternal life of holy love. Within the life of the Trinity, the Father gives himself in love to the Son, the Son responds in love to the Father, and the Holy Spirit is fully united in that eternal fellowship. God is not a solitary individual but an eternal communion of love.
This eternal reality is revealed in God’s work of salvation. In what theologians call the “economic Trinity,” the Father sends the Son into the world, and the Son sends the Holy Spirit to empower and guide the Church. The God who is eternally sending and giving in love acts in history according to his nature.
This has profound implications for Christian discipleship. When we place our faith in Christ, we are adopted into the life of this Triune God. We become members of a sending family. To be a Christian is not merely to receive God’s grace but also to participate in God’s mission. Just as the Father sent the Son and the Son sent the Spirit, so Christ sends his Church into the world to bear witness to the gospel.
The Church, therefore, must reflect the life of the God it worships. A healthy church is not inward-focused, self-protective, or content merely to maintain itself. It is a sending community—raising up disciples, sharing the gospel, serving its neighbors, planting churches, supporting missions, and participating in God’s redemptive work in the world. As we grow in the life of the Trinity, we discover that God’s sending heart becomes our own.
Join us as we explore the mystery, beauty, and mission of the Holy Trinity and what it means to live as people who have been sent by the God who eternally sends.
