The apostles wrote during a tumultuous time in the history of the church. They had to correct misunderstandings of the gospel, including who were truly part of the church as well as a broad range of misunderstandings of what God’s grace really meant.

In his first letter, John addressed early church teachings that openly tolerated worldly sin while still claiming one could be in fellowship with Jesus. The apostle shuts that down by saying that only those who “walk in the light” (1 John 1:7) have a true relationship with God. But that doesn’t mean believers in Christ don’t sin (v. 8). Instead, it means that because of their relationship with God, they can confess their sin and enjoy both forgiveness and fellowship no matter how heavy the burden of regret (v. 9).
