The sermon centers on the urgent need for spiritual assurance, using Hebrews 6:19's image of hope as a sure anchor to emphasize that genuine faith must be grounded in confident knowledge of one's salvation. Drawing from Luke 16's parable of the rich man and Lazarus, it contrasts eternal destinies—eternal comfort for the humble believer and torment for the unrepentant, regardless of earthly status—while warning that mere religious activity or familiarity with Christ does not guarantee salvation, as illustrated by Matthew 7:21–23. The preacher shares a deeply personal testimony of his father's last-minute conversion, underscoring the reality of divine judgment and the critical importance of personal, heartfelt faith. He challenges believers to examine their assurance and actively share the gospel, framing every Christian as a spiritual travel agent entrusted with the life-changing message of salvation. Ultimately, the message calls for decisive, honest response—either with confident assurance or a humble, urgent plea for certainty—before it is too late.
