In this sermon, Pastor Jason addresses the topic of unforgiveness as part of the "Unsubscribed" series. He explains that forgiveness is necessary for all relationships and has both vertical (with God) and horizontal (with others) dimensions. Using John 21 as his text, he examines Jesus' model of forgiveness through His restoration of Peter after Peter's denial. The pastor highlights that forgiveness begins with invitation rather than condemnation, restores through honest conversation, and calls us to a higher purpose. He emphasizes that Jesus is our model for forgiveness, and the cross demonstrates the ultimate example of forgiveness. The sermon concludes with signs of unforgiveness (avoidance, negative thoughts, passing hurt to others, disconnection from God) and signs of forgiveness (peace in their presence, praying for them, offering kind actions and words, growing intimacy with God).
