The Corinthian Christians were saved as a fruit of the Apostle Paul’s ministry. The gospel that he preached indeed were effectual to the conversion of souls and how they renounced their idols and come to faith in Jesus Christ. It was a well-known fact that an undeniable change has taken place in their lives. There was no necessity for any letter to be written on pen and paper to authenticate the Apostle Paul’s love for them.

The Apostle Paul begins this chapter with the question, “Do we begin again to commend ourselves?” The again does not imply that he had commended himself previously. Rather, it simply means that he had been accused of doing so, and now he anticipates the repetition of such a charge against him. [William MacDonald]

The testimony of the gospel team led by the Apostle Paul went about their mission work with sincerity of heart, preaching the gospel in the fear of God. They were mindful of the spiritual mandate placed upon them and were careful to speak the truth according to the Word of God. Venturing not to speak beyond what the Word of God says, they stood behind the Word of God.

If God has not forgiven us, we are still in our sins. If God has not forgiven us, we are awaiting the fearful wrath and judgment of God. But because God has forgiven us through the unmerited favour of God through the finished work of Jesus Christ on the cross, we no longer are at enmity with God but was reconciled to the Father in a blessed familial relationship enjoying peace and joy in our hearts.
