What does the Bible say about judgment and grace in Zephaniah?

In Zephaniah, God declares His intention to execute judgment on unfaithful Israel due to their inability to uphold the covenant of works. The message of judgment emphasizes that the people mixed their worship of God with idolatry, leading them astray. However, amidst the pronouncements of judgment, there is a clear indication of grace; we see that God prepares a sacrifice and sanctifies His guests. This foreshadows the ultimate sacrifice of Christ, in whom grace abounds and judgment is satisfied.
