‘For the anger of man does not work the righteousness of God.'
‘The anger of man.' Note the emphasis on ‘of man' or ‘of a man' (andros is used rather than anthrowpos). It is of course different with God. But the point is that His anger is always rightly directed and has behind it a continuing underlying compassion. In His case it is always a just anger against sin coming from One Who is without sin. But man is to be more wary, ‘be you angry and sin not, do not let the sun go down on your wrath' (Ephesians 4:26). In man's case it is to be both righteous and brief.
