Unexpected Changes, Complete Joy
Pastor Tan Thai · Jan 5, 2020
This sermon reflects on the unexpected changes in the apostle Paul's life during his second missionary journey, teaching that God's purposes are always better than human plans. When we submit to Him even without understanding the reasons, He grants a fullness of joy that exceeds all expectation.
The sermon opens by reflecting on the New Year 2020 resolutions that many people make — from health and work to spiritual life. The pastor emphasizes that while believers make many plans, unexpected changes are certain, and the faithful person accepts these changes in trust. Proverbs 19:21 is quoted: "Many are the plans in a person's heart, but it is the Lord's purpose that prevails."
The core of the sermon focuses on Paul's second missionary journey (Acts 15–16). Paul's original plan was to travel with Barnabas to revisit established churches, but a sharp disagreement over John Mark led to their separation. Subsequently, the Holy Spirit twice prevented Paul from preaching in Asia Minor (Asia and Bithynia), redirecting him to Troas and then to Macedonia in Europe. This marked the first time in church history that the Gospel was preached on European soil.
Throughout these unexpected changes, God continually provided Paul with faithful companions: Timothy at Lystra and the physician Luke at Troas. The first church in Philippi was planted, and it became the most beloved of Paul's churches — faithfully partnering with him, giving generously, and bringing him complete joy even as he wrote from prison. The letter to the Philippians, written from a Roman jail, overflows with the theme of joy as living proof of God's grace given through unexpected change.
The pastor applies the message through personal stories — including his mother suffering a stroke on the very day of her final immigration interview after ten years of waiting, and his own journey from literature and teaching to theology and pastoral ministry. These experiences illustrate that disappointment when plans change is entirely natural, but believers are called to hold fast to faith in God's faithfulness and love, as affirmed in Proverbs 3:5-6 and Jeremiah 29:11.
The sermon concludes with the affirmation that God changes our plans not to harm or punish us, but out of His boundless love and infinite wisdom — to give us a complete joy we would forfeit if we insisted on our own way. The pastor proposes renaming the sermon "Unexpected Changes, Many Complete Joys" as a confession of faith for the new year.
