Sermon this Sunday is on righteous anger from Ephesians 4:26.
If we are commanded and expected to be angry about certain things then our anger (in order to be righteous) must replicate or imitate the anger of God in some way.
Thinking along this line, I took a couple of hours tracing the theme of the wrath of God.
This was humbling and helpful to me.
Look up a couple of the texts that stood out to me:
Nahum 1:1-6
Psalm 7:11
Psalm 76:7
Revelation 19:11-15
Here is a heavy quote from A.W. Pink
The wrath of God is His eternal detestation of all unrighteousness. It is the displeasure and indignation of Divine equity against evil. It is the holiness of God stirred into activity against sin. It is the moving cause of that just sentence which He passes upon evil-doers. God is angry against sin because it is a rebelling against His authority, a wrong done to His inviolable sovereignty. Insurrectionists against God’s government shall be made to know that God is the Lord. They shall be made to feel how great that Majesty is which they despise, and how dreadful is that threatened wrath which they so little regarded. Not that God’s anger is a malignant and malicious retaliation, inflicting injury for the sake of it, or in return for injury received. No; while God will vindicate His dominion as Governor of the universe, He will not be vindictive.
