What does Psalm 73:27 mean?

At the beginning of this psalm Asaph was suffering a crisis of faith, thanks to a short-range view of the wicked (Psalm 73:2–3). They prospered and were healthy, while God's people were suffering (Psalm 73:4–14). Now, after pondering the whole matter before the Lord in the temple (Psalm 73:15–18), he takes the more appropriate, long-range view of the wicked: they were far from God and destined to perish.

Asaph understood that God judges everyone who violates His laws. Most likely, the well-to-do evil ones Asaph was thinking of were unfaithful Israelites. It is also true that everyone who fails to believe on God's Son is condemned already (John 3:18). John 3:36 says categorically: "Whoever does not obey the Son shall not see life, but the wrath of God remains on him." At the final judgment, the great white throne judgment, all unbelievers, regardless of their rank and station in life, will be consigned to the lake of fire. This judgment is called the second death because it causes separation from God for eternity (Revelation 20:10–15).
