The sermon concludes a 28-month journey through the Book of Romans with a powerful call to be established in faith through the unchanging gospel of Jesus Christ, which is the sole power for both salvation and spiritual stability. Centered on Romans 16:25–27, the message emphasizes that the mystery of God's plan—the inclusion of Gentiles into the body of Christ through faith in Christ's death, burial, and resurrection—was once hidden but is now revealed through Scripture and the preaching of the apostles. The preacher underscores that true establishment comes not from human effort, emotionalism, or cultural trends, but from faithful adherence to the Word of God, prayer, and obedience to the faith. He warns against distractions, legalism, and false gospels, affirming that the church's foundation is Christ alone, revealed in Scripture, and that unity across geographic and denominational lines is rooted in shared belief in the gospel. The ultimate purpose of all things is to glorify God, the only wise one, through Jesus Christ, and the church's mission is to proclaim this truth with unwavering commitment.
