That's What He Said: Take Sin Seriously (Worship 3/1/26)

The passage from Matthew 5:27–30 extends adultery beyond an act to a condition of the heart, insisting that visual input and inward desire have direct moral and eternal consequences. Jesus uses stark language—gouging the eye, cutting off the hand—to demand decisive, violent action against anything that entraps the heart in sin. The text connects what the eyes take in to the heart’s bent and then to outward behavior, making the point that unchecked inward inclination can shape conduct and threaten eternal standing.

Scripture and later writers push the same resolve: sin must die or it will kill the soul. John Owen’s formulation—kill sin or be killed by it—frames mortification as an active, ongoing work. Paul’s call in Colossians 3:5 catalogs the inward sins (sexual immorality, impurity, lust, evil desires, greed) that require intentional putting to death, while the Psalms model a posture of hatred toward what corrupts the heart. Those exhortations demand both hatred of sin and practical disciplines to uproot it.

Eternity anchors the urgency. Matthew’s language about Gehenna and Jesus’ frequent warnings about reward and punishment press the posture of mortality into daily living: choices here bear on everlasting realities. That urgency fuels both personal holiness and compassionate mission. A genuine love for others seeks their eternal good, not their condemnation, and Christians should speak and live in ways that lead toward Christ rather than away.

Holiness receives a concise definition: love God with all faculties and love others as Christ loved. The Spirit produces that vertical and horizontal transformation, but humans must replace sinful habits with spiritual practices—prayer, scripture, fasting, community, and sacramental life—to change input and form the heart. Communion functions as a potent reminder of forgiveness, grace, and the call to live as the body of Christ redeemed by his blood.

The call closes with a summons to courageous discipleship: hate sin, put it to death with decisive practices, keep eternity before the eyes, and embody holiness that seeks the salvation of others. The life that follows these demands looks sacramental, disciplined, and missionary—rooted in grace and shaped by the ongoing work of the Holy Spirit.

Key Takeaways

• 1. Remove the bent toward sin Hardened inclinations originate in the heart’s default pathways. Attention to what the eyes and mind regularly consume rewires desire over time; therefore, treating inward leaning as formative allows intentional redirection toward life with God. Cultivate immediate refusal when temptation arises rather than rationalizing slow drift. [40:04]
• 2. Kill sin with decisive action Mortification requires violent, resolute choices, not polite avoidance or passive remorse. When affections remain unchecked, small compromises become habits that define character; decisive measures sever those footholds before they produce deeper bondage. Consider what practical “sledgehammer” actions will remove recurring snares from daily life. [36:58]
• 3. Keep eternity constantly present Eternal realities sharpen moral urgency and reshape daily priorities. Regular reflection on heaven and hell prevents spiritual amnesia and fuels both personal holiness and compassionate mission toward others. Let mortality inform choices so that life aligns with lasting values rather than temporal gain. [50:33]
• 4. Replace sins with spiritual practices Sinful patterns retreat only when new spiritual rhythms occupy the same space. Swap reactive behaviors—excess screen time, secret indulgences—with prayer, Scripture, fasting, and Christian fellowship to reorient input and formation. These practices recondition desire and sustain holiness over the long haul. [60:21]
