2 Corinthians 1-3

In 2:5-11 Paul offers guidance for the early believers on forgiveness. When someone in the assembly is living in sin the goal of the community is forgiveness. That reflects God's goal as well. Granting forgiveness implies that the sinner wants forgiveness. To desire forgiveness require a change of heart regarding the offense. The sinner must call their actions sin. That is the first step in receiving  forgiveness.
