How do we know that God's wrath is real?

The concept of God's wrath is affirmed in biblical texts, particularly in Revelation 6, where it is described as the 'great day of His wrath' which has come. This implies a definitive judgement that all men, especially the wicked, will face. The cry for the mountains and rocks to fall on them indicates the terror that grips those who have lived in opposition to God's grace. Additionally, the fulfillment of prophetic warnings in both the Old and New Testaments accentuates the certainty of God’s final judgment. It is a reminder that rejecting God's word leads to inevitable consequences, culminating in eternal separation from His presence and an experience of His righteous wrath.
