Psa 7:11 God is a righteous judge, and a God who feels indignation every day.
Psalms 7 is an appeal by King David for God to judge the world. David invites God to rise up and judge his enemies and even judge himself. Verse 11 is a claim by David that God is predisposed to justice. God is affected every day by the actions of human being. God “feels” indignation.
Verse 12 follows this description with God waiting for man’s repentance. If man does not repent, God will unleash the punishments He “prepared” for man.
None of this makes sense in the context of an impassible God, one who cannot be affected by His creation. Instead, God sees and reacts. God is hurt and moved. God responds to man’s actions.
