Ephesians 4:26 — 'be angry and do not sin; do not let the sun go down on your anger' is about harboring anger in your own heart, not about resolving every marital dispute before bed.

Mike argues the verse is commonly misread as a command for married couples to resolve every disagreement before sleeping. He clarifies it addresses not harboring anger in one's own heart — regardless of whether the relational problem is solved. Verse 27 then connects prolonged anger to giving the devil an opportunity. He ties this to Genesis 4 where God warns Cain about sin crouching at the door before Cain murders Abel — the internal festering of anger precedes and enables the sinful act.
