What does the Bible mean when it says 'the two become one flesh?'

The sermon centers on the biblical design for sexuality as a sacred, holistic gift meant to reflect the profound union between Christ and the Church, grounded in the truth that believers are not their own but belong to God, having been bought with the price of Christ's blood. It confronts the cultural distortion of sex through the lens of 1 Corinthians 6, rejecting the Gnostic notion that the body is disposable and emphasizing that sexual intimacy—when confined to marriage—creates a deep, irreversible union of body, soul, and spirit, mirroring the covenantal relationship with Christ. The message warns against the destructive consequences of sexual immorality, not merely as a moral failure but as a spiritual betrayal that defiles the temple of the Holy Spirit and undermines the believer's identity in Christ. Ultimately, the sermon calls for a holy reorientation of the body, mind, and heart toward God, urging believers to flee sexual sin and instead glorify God in their bodies by cherishing the sacred gift of marriage as a living testimony to divine love.
