The central message of this sermon is that the ultimate purpose of the gospel is not human happiness, but the eternal glorification of the only wise God through Jesus Christ. Drawing from Romans 16:25–27, the preacher emphasizes that believers are strengthened and established by God through the gospel, the preaching of Christ, the revelation of divine mystery, the prophetic Scriptures, and a life of obedient faith. This divine establishment enables believers to proclaim the gospel to all nations, fulfilling God's eternal command and demonstrating His universal sovereignty. The sermon underscores that true worship and glory to God are only possible through Jesus Christ, who uniquely reveals the Father and provides the righteousness necessary to approach Him in worship. Ultimately, the gospel's purpose is to magnify God's infinite wisdom and glory, a truth confirmed by Scripture and affirmed in the believer's life and worship.
