2 Peter 1:1-11

The Living Among the Walking Dead

In this sermon from Ephesians 4:17–24, Pastor Zack contrasts two radically different ways of life: the dark, futile existence of those alienated from God and the new life granted to those united to Christ. Paul diagnoses the unconverted heart as blind and enslaved to deceitful desires, then proclaims the gospel deliverance—God rescues sinners by renewing the mind, giving new affections, and calling them to put off the old man and put on the new. Christians are not merely informed differently; they have been buried and raised with Christ and are now created to walk in true righteousness and holiness. This sermon presses the truth of union with Christ into daily practice. What does repentance look like on Monday morning? How do work, relationships, media habits, and private thoughts become arenas of worship? Pastor Zack offers concrete steps for mortifying sin and cultivating godly counter-habits, reminding us that while sin is deliberate, grace is decisive. The call is clear: live as those who have been made alive in Christ, no longer walking as the dead, but as new men and women renewed in the spirit of the mind. #NewMan #BiblicalChristianity #UnionWithChrist

Dead Men Walking: A Biblical Anthropology

In this powerful sermon, Pastor Zack unpacks one of the most sobering and hope-filled passages in Scripture—Ephesians 2:1–5. We were not merely sick in sin; we were dead. Spiritually lifeless. Children of wrath by nature, not victims of sin but willing participants in rebellion. Yet into that graveyard of souls came the two most beautiful words in all the Bible: “But God.” With mercy richer than our rebellion and grace deeper than our depravity, God made us alive together with Christ. From the valley of dry bones in Ezekiel to the heart of Paul’s gospel, Pastor Zack shows that regeneration is not moral reform—it is resurrection. The heart of stone is replaced with a heart of flesh. The sinner is raised, renewed, and restored by grace alone, through faith alone, in Christ alone. Soli Deo Gloria.

Christ, The Redeemer

In this sermon on Ephesians 1:7–10, Pastor Zack unfolds the riches of God’s redeeming grace in Christ. Redemption is not a vague hope but a blood-bought reality—secured by the Son, lavished upon sinners, and rooted in God’s eternal plan to unite all things in Christ. Pastor Zack weaves together the story of Ruth and Boaz, showing how God’s providential redemption in the fields of Bethlehem points forward to the greater Redeemer, Jesus, who pays the full cost for His bride. Just as Ruth found refuge under the wings of Boaz, so too the church finds everlasting security under the wings of Christ, our Redeemer. The sermon also warns against presuming upon God’s kindness. His patience is meant to lead us to repentance, not complacency. Yet for those who belong to Christ, the riches of His grace are beyond measure, His forgiveness is without end, and His purposes are unshakable. In Christ, we are brought into the hope of glory, joy in our labor, and the assurance that all of history will be summed up in Him. Join us as we look at the glory of the gospel through Paul’s words and Ruth’s story, and rejoice in the Redeemer who unites heaven and earth. #GraceUponGrace #Redemption #Forgiveness

The Shadow of Hope

In this week's sermon, Pastor Zack examines the poignant account of King Hezekiah in 2 Kings 20, confronting the reality of death and the profound mercy of God. Drawing from Ecclesiastes, Chronicles, Proverbs, and Titus, we see how Hezekiah's crisis leads to spiritual renewal, heartfelt worship, and the restoration of pure devotion among God's people. Pastor Zack emphasizes that life's brevity and the inevitability of death do not diminish its value, but instead enrich our moments with gratitude, love, and holy reverence toward our Creator. Yet, the story of Hezekiah also offers sobering lessons on humility and obedience. Despite his faithfulness, Hezekiah fell into pride, reminding us all of our need for constant vigilance and humble dependence upon the Lord. Join us as we reflect on the importance of setting our spiritual house in order, confronting idolatry, standing firm in sound doctrine, and living with joyful courage under God’s sovereign care. #LifeAndDeath #Reformation
