The sermon explores Paul's declaration in Romans 1 that he is a debtor to all people, clarifying that this obligation stems from his apostolic commission to preach the gospel rather than a financial debt. It distinguishes between the believer's duty to share God's grace with others and the impossibility of earning salvation through works, emphasizing that Christ alone paid the sin debt as the Kinsman Redeemer. The message highlights the urgency of evangelism by referencing Paul's desire for spiritual fruit among the Gentiles and the sovereign guidance of the Holy Spirit in his ministry. By connecting themes of grace, truth, and the bearing of spiritual fruit, the preacher urges listeners to utilize their God-given gifts to serve others and spread the good news. The central intent is to comfort believers with the assurance of free grace while simultaneously convicting them to fulfill their mandate as witnesses to a lost world.
