Erlo Stegen emphasizes God's intimate knowledge of each individual, highlighting that despite the vastness of humanity, God has good plans for everyone, even those who have sinned. He reflects on Israel's return from exile and their subsequent rejection of idol worship, illustrating God's mercy and the importance of confession. Stegen reminds us that God is aware of all our thoughts and sins, and that true forgiveness comes through confessing and forsaking our sins. He encourages believers to find comfort in the assurance of forgiveness through Jesus' blood, especially when facing death. The sermon concludes with the reminder of the blessedness of having one's sins covered and the preciousness of a saint's death in God's sight.
