The apostle Paul, in this verse, testifies to the gospel of God’s grace. The gospel is a message of grace, a reminder that salvation is not earned by our efforts but is freely given by God through Jesus Christ. Our testimony of the gospel is a testimony of grace—it is God’s unmerited favor that allows us to be reconciled to Him. When we share the gospel, we are sharing the story of how God’s grace has transformed our lives. This grace is available to all people, and it is through faith in Christ that we receive it. Paul’s testimony points to the centrality of grace in the gospel message. The gospel is not about what we can do for God but about what He has done for us. Our evangelism should always point back to the grace of God that saves, heals, and restores.
