Why is it necessary to warn of judgment in preaching?

In Acts 13, Paul concludes his sermon with a clear warning of impending judgment, emphasizing the seriousness of rejecting God's offer of salvation through Christ. This warning serves a dual purpose: first, it highlights the gravity of sin against a holy God, and second, it compels listeners to seek forgiveness and reconciliation. The biblical message consistently stresses that judgment is a reality for those who do not believe. Preachers are called to address this solemn truth, ensuring that the love of God is framed within the context of divine justice, which ultimately leads individuals to recognize their need for a Savior. Such warnings enhance the gravity of the gospel message and invite repentance as an essential response to God's grace.
