How did Paul view his role in preaching the gospel?

In Romans 1:14, Paul states, 'I am a debtor both to Greeks and to Barbarians, both to wise and to unwise.' He recognized that because of his own experience of grace and salvation, he was obligated to share the good news with others. Paul understood that he had been transformed from a blasphemer to a proclaimer of the gospel. This deep sense of indebtedness was fueled by gratitude to God for His mercy shown to him despite his sinful past. This perspective emphasizes the importance of evangelism and the call for all Christians to share the gospel, as it is the means through which God brings His elect to faith.
