Salvation is God s mercy to the wicked and a path which God has given hope to the hopeless. Anger that is just is anger under God s control. Never get angry without a just cause. God s anger is at murder and profaning His house. Eyes that are fixed on Christ will find mercy.
Righteous indignation falls on sin and sin is no more.
KP P.S. Anger is an emotion to harm what has caused perceived wrong.
