One Covenant Church Sermons

Sermon series: 1 Timothy: Under One Roof To address false teaching, Paul calls Timothy to order the church’s worship according to God’s Word, because worship shapes God’s people. True worship is marked by prayer for all kinds of people and reflects the beauty of God’s created order—all to exalt Jesus Christ, the one mediator between God and humanity. Preacher: Tan Huai Tze Date: 18 January 2026

Sermon series: 1 Timothy: Under One Roof Before entrusting Timothy with the charge to preserve and proclaim the gospel, Paul gives a personal testimony of how he had been called to the service of Christ. It was according to God’s mercy and grace, and therefore is an encouragement to Timothy to press on because of his love for Jesus. Preacher: Tan Huai Tze Date: 11 January 2026

Sermon series: 1 Timothy: Under One Roof The apostle Paul wrote 1 Timothy to his protégé in ministry to encourage him in the work of ministry. However, this was not simply written to Timothy, but an authoritative letter for the church of God. As Paul wrote against the false teachings which were spreading within the church, he emphasised the importance of right Gospel doctrine for right living. Thi...

Sermon series: Topical Based on a framework developed by Glen Scrivener, this message explains that God is a loving union of 3, and therefore, He is love; that the world is shaped by 2 representatives: Adam and Christ. Adam brought death, while Jesus brings life; and that we are born 1 with Adam, but can become 1 with Christ by faith. Preacher: Tan Huai Tze Date: 28 December 2025

Sermon series: Isaiah 1-12: Sinful People, Saving God Isaiah 12 is a song of praise in response to all God had done for His people in Isaiah 1-11.

Preacher: Tan Huai Tze Date: 21 December 2025

Sermon series: Isaiah 1-12: Sinful People, Saving God Despite the apparent hopelessness as a result of God's judgment, Isaiah 11 gives us a surprising image in the form of a shoot from the stump of Jesse. God promised the coming of a King, whose reign shall be marked entirely by justice and peace. This messianic King is now raised as a signal to the nations and is gathering people from everywh...

Sermon series: Isaiah 1-12: Sinful People, Saving God As an instrument of divine judgment, Assyria was raised up by God as a rod of His anger against His people. At the same time, God will not allow His people to be completely obliterated. He will preserve a faithful remnant for Himself, as He had done in the past. For this reason, those who are faithful have no need to be fearful, even when affli...

Sermon series: Isaiah 1-12: Sinful People, Saving God Before God brings peace and joy (Isaiah 9:1-7), He confronts the evil that destroys His world. Israel’s arrogance, stubbornness, and mistreatment of others invite His judgment—and so do ours. But Christ bore that judgment and offers us His mercy and peace. Preacher: Tan Huai Tze Date: 30 November 2025

Sermon series: Isaiah 1-12: Sinful People, Saving God In this passage, God meets His people with both firmness and warmth: He warns of calamity, but guides them through confusion, and gives them the hope of the coming light.

Sermon series: Isaiah 1-12: Sinful People, Saving God Isaiah 7 tells of King Ahaz, who faced a crisis and chose fear over faith, trusting Assyria instead of God with devastating consequences. God still pursued him and then gave him the sign of Immanuel, pointing forward to Jesus. Christ bears our weight, lifts us to safety, and invites us to stand firm by trusting Him. To stand firm in faith is to...

Sermon series: Isaiah 1-12: Sinful People, Saving God Isaiah 6 is an important pivot in the opening section of the book. As the prophet Isaiah beheld the holiness of God, he recognised that he is undone before the Lord. At the same time, God showed grace to the prophet and commissioned him for ministry to a rebellious people. If what happened to a man of unclean lips could happen to a nation of un...

Sermon series: Isaiah 1-12: Sinful People, Saving God Isaiah 5 reveals a God who has lovingly cared for and richly blessed His people, planting them like a prized vineyard and providing everything they need to flourish. Yet instead of bearing good fruit, they produce only stinking grapes. Through six woes, God exposes how His people have corrupted His blessings and despised His Word, leaving judgm...

Sermon series: Isaiah 1-12: Sinful People, Saving God God brings His straying people back by taking away their reliance on power, and their boasting in beauty. Through Christ, He gives them all that power and beauty promise, but cannot deliver. Preacher: Tan Huai Tze Date: 26 October 2025

Sermon series: Isaiah 1-12: Sinful People, Saving God God’s people in Isaiah’s time were full—full of wealth, power, and idols—but empty of trust in Him. They had lost their way, putting their hope in what they had, instead of in who God is. Isaiah warns that a day is coming when all human pride will be humbled before the terror and splendour of the Lord. Our only hope is to hide in the Rock, Chri...

Sermon series: Isaiah 1-12: Sinful People, Saving God When God’s people are unfaithful to God, this affects all of their social relationships.

God will act to bring His people back through judgment and redemption, and promises them a glorious future hope which is ultimately fulfilled in Jesus. Preacher: Ta...

Sermon series: Isaiah 1-12: Sinful People, Saving God The book of Isaiah opens with God confronting His people like a grieving father betrayed by his children. They have rebelled against Him completely, and their empty worship only wearies Him. Yet instead of letting judgment fall, God issues an unthinkable invitation, “Though your sins are like scarlet, they shall be white as snow”. He offers the...

Sermon series: 1 John: Knowing You Are Alive In the concluding passage of this letter, the apostle John draws everything together under one great theme: confidence. He desires that we live with confidence before God in this uncertain world. This confidence is grounded in what we know, particularly the fact that God saved us through Jesus Christ, hears us through prayer, and keeps us through the pr...

Sermon series: 1 John: Knowing You Are Alive John has shown that God’s children are known by love and obedience. Now, he assures believers that their faith in Jesus is grounded in God Himself. The Father gives us victory over the world through faith (1 John 5:1–5). The Spirit testifies to the truth of who Jesus is (1 John 5:6–10). The Son gives us eternal life (1 John 5:11–12). Our confidence rest...

Sermon series: 1 John: Knowing You Are Alive Loving one another is a mark of being a true follower of Jesus. But this kind of love is only made possible for the follower of Christ because God is love in His very nature, God has loved by giving His Son as a sacrifice for sin, and God continues to love by living in us, and is accomplishing the goal of His love for us. Indeed, we love because He has...

Sermon series: 1 John: Knowing You Are Alive The gift of the Holy Spirit is so precious that it will be counterfeited. Because of that, John wants us to “test the spirits” (1 John 4:1) to see if they are from God because many false prophets have gone out into the world. John shows that those who have the Holy Spirit will believe in Jesus, stake their lives on Him and stay in the church that He is...

Sermon series: 1 John: Knowing You Are Alive This passage shows us that even as genuine believers, assurance that we are truly children of God is something we need to fight for. However, the foundation of that assurance is not what we do, but what Christ has done. We receive this by faith, and the result is a life lived in faith, obedience and love. Preacher: Aaron Akins Date: 31 August 2025

Sermon series: 1 John: Knowing You Are Alive The apostle John focuses on the social test in these verses, i.e., whether one has love for a fellow believer. Love for one another is not a duty of burden, but a gift of assurance that we truly know God. Since we have been brought from death to life, we are no longer called to treat one another, as if we're still living in the darkness. Rather, we...

Sermon series: 1 John: Knowing You Are Alive In this passage, we discover who the true children of God are, what they will be, and how they live now. In His love, God makes us His children through Christ. And when we see Christ when He comes again, we will be like Him. And so today, in light of that hope, we live lives joyfully dependent and lovingly obedient to God, expressed in our practical act...

Sermon series: 1 John: Knowing You Are Alive In his love for his readers, John issues a stern warning about the danger of the antichrists. They are those who leave the fellowship of the church, and who deny that Jesus is sent by God, and is indeed the Son of God. They are deceptive. In order to resist them, we need to let God’s truth abide in us, and we need to continue to abide in God. And what w...
