There is a revelation (apokalupsew) of God's wrath for both in the day of wrath and righteous judgment (dikaiokrisia, a late compound word, in LXX, two examples in the Oxyrhynchus papyri, only here in N.T.). See 2 Thessalonians 1:5 for dikaia krisew. Paul looks to the judgment day as certain (cf. 2 Corinthians 5:10-12 ), the day of the Lord ( 2 Corinthians 1:14 ).
