The sermon examines the biblical markers that confirm genuine salvation and distinguish true believers from mere professed Christians. It outlines three primary evidences of eternal life: belief in Jesus as the biblical Christ, love for God and His family, and obedience to His commandments through divine grace. The preacher emphasizes that spiritual rebirth is a sovereign act of God rather than human effort, enabling believers to overcome the world system through faith in Christ. This victory is rooted in union with Jesus, who has already conquered sin and death on the cross. The message concludes by urging self-examination and reliance on Christ's righteousness for assurance and holy living.
