Consider this verse: God is a just judge, and God is angry with the wicked every day.(Psalm 7.11)
Why is God angry? Because He is just, He knows what’s right and hates what is wrong.
What is anger or indignation? It’s a feeling God gives us to signal that something is wrong. In the same way, anger is a feeling that issues from God and is born in the heart of those who refuse to accept injustice, and to see evil and wrong prevail. Anger comes from God Himself. It originates from His righteousness. Human beings, as an extension of God, already have this feeling embedded in their nature.
The opposite of anger is passivity — accepting problems, justifying and finding excuses for them. “It’s life.” “I’m not the only one, many people go through this.” “Divorce is normal these days.” “We’re in a recession.”
When a person’s thoughts are aligned with God’s thoughts, that person feels angry every day too, because that is the mind of God.
The question is: What do we do with this anger and indignation? Those who don’t know what to do, end up either accepting their situation or doing something crazy, like taking out their anger on others.
But those who are connected to God’s thoughts are also guided by Him on what to do with their anger. And when they act upon this direction, change happens and justice prevails.
