Psalm 7:1-13
"God is a righteous judge, and a God who feels indignation every day.  If a man does not repent, God will whet his sword; he has bent and readied his bow; he has prepared for him his deadly weapons, making his arrows fiery shafts."  Psalm 7:11-13
David begins his prayer acknowledging the LORD God is his only refuge and savior.  He is being accused unjustly and is crying out for God to vindicate him.  He knows God said, "You shall not bear false witness against your neighbor."  His accusers are doing just that.  He acknowledges God is the righteous judge who knows minds and hearts and is his only Shield.
Then David says God feels indignation every day.  He infers God is indignant against those he describes in verse nine as "Oh, let the evil of the wicked come to an end." 
The definition of indignation is anger aroused by something unjust, unworthy or mean.  Do you think of God as being indignant every day about the evil and wickedness of His creation?  God's anger against the wicked continues as long as their wickedness continues.  Romans 2:5 says, "But because of your hard and impenitent heart you are storing up wrath for yourselves on the day of wrath when God's righteous judgment will be revealed."  Just as the "Steadfast love of the LORD never ceases, his mercies never come to an end; they are new every morning," (Lamentations 3:22-23) so, too, is His anger against the wicked.  (John 3:36)
That is always the choice God holds before humanity, indignation or mercy.  That is what David says in the next two verses, "If a man does not repent...he has prepared for him his deadly weapons" for the wages of sin is death.  Even with God's daily indignation against evil, there is, also, the offer of peace.  "If a man does not repent" holds the offer of repentance with the promise of mercy.  Ezekiel 33:11 says, "As I live, declares the LORD God, I have no pleasure in the death of the wicked, but that the wicked turn from his way and live; turn back, turn back from your evil ways, for why will you die?" 
LORD God, thank You for the prayers of David.  Thank You for the clarity of insight David had of both himself and You.  I don't think of Your daily indignation against evil.  Evil just seems like a natural part of the world in which I live.  I know there is coming a day in which You will judge the quick and the dead, but I don't think of the wicked storing up wrath for themselves in their rebellion.  Thank You for the mercy that accompanies Your gift of repentance.  Thank You for being my refuge, savior, and shield
