My college friend Bill Tobias has served as a missionary on a Pacific island for many years. He tells the story about a young man who left his hometown to seek his fortune. But a friend took him to church where He heard the good news Jesus offers, and he trusted Christ as his Savior.

The young man wanted to take the gospel to his people and looked for a missionary to reach his people who were “steeped in sorcery.” But the missionary told him to simply “go tell them what God did for you.” And that’s what he did. Several people in his hometown received Jesus, but the biggest breakthrough came when the town’s witch doctor realized that Christ was the “way, the truth, and the life” (John 14:6). After he put his faith in Jesus, he told the whole town about Him. Within four years, the witness of one young man had led to the establishment of seven churches in the region.

In 2 Corinthians, Paul sets forth a clear plan for introducing the gospel to those who don’t yet know Christ—and it aligns with what that missionary told the young believer in Jesus. We are to be “Christ’s ambassadors”—His representatives “as though God [is] making his appeal through us” (5:20). Every believer has a unique story to tell of how Jesus made them a “new creation . . . who reconciled” them to God (vv. 17–18). Let’s tell others what He’s done for us.
