The concluding part of this series is drawn from Romans 16:17–20, delivers a timely and urgent call to spiritual vigilance, urging believers to mark and avoid those who cause divisions contrary to sound doctrine. Centered on the warning against individuals who serve their own desires—symbolized by the 'belly'—rather than Christ, the message emphasizes that such people deceive through flattery and exploit unresolved personal pain to sow discord. Pastor Friesen underscores that true spiritual maturity involves confronting past wounds, surrendering selfish ambitions, and cultivating a heart that gives rather than takes, all while remaining unified under Christ's lordship. Drawing on Paul's exhortation to follow godly examples and to reject self-centeredness, the sermon calls the church to prioritize divine glory over human approval, to renounce the fleshly appetites that lead to division, and to live as a unified body in which every member serves for the good of all, not for personal gain.
