The sermon centers on the Christian imperative to forgive others as God has forgiven us, drawing from key passages in 1 Peter, Romans, Ephesians, and Matthew's model prayer. It emphasizes that forgiveness is not denial of harm, nor is it reconciliation, but a deliberate choice to release anger and break the cycle of retaliation, modeled by Christ on the cross and Stephen in his martyrdom. The preacher underscores that true forgiveness begins with receiving God's grace, which enables believers to extend mercy even when offenders never repent. He calls for practical application, especially within the home, and warns that unforgiveness reveals a lack of personal repentance, while forgiveness frees both the giver and the receiver from inner torment. Ultimately, the sermon calls the church to embody Christ's example, trusting that God alone judges rightly, and to live as sons of the Father by practicing mercy and grace.
