In this powerful message from 1 Corinthians 3:16–17, we see Paul’s progression from building on the foundation of Christ to the stunning reality that we are the very temple of God. This sermon challenges believers to move beyond casual Christianity and embrace their identity as the dwelling place of the Holy Spirit, where unity, holiness, and love are not optional—but essential. If God truly lives among His people, then how we treat one another and live together becomes sacred, calling us to build up—not tear down—what God calls His holy house.
