What does Revelation say about God's wrath and the sealing of His servants?

In Revelation, the sealing of God's servants signifies a protection from His wrath that is present on the earth. As seen in Revelation 7:1-3, God's wrath is restrained until His servants, those who are His chosen ones, are sealed. This shows that God’s judgment is purposeful and that He is merciful in waiting for His elect to come to faith before pouring out His full wrath. Thus, the sealing provides divine assurance for believers that they will not face the ultimate destruction that awaits those outside of Christ.
