Psalm 109:26-31

26 Help me, O Lord my God!Save me according to your steadfast love!
27 Let them know that this is your hand;you, O Lord, have done it!
28 Let them curse, but you will bless!They arise and are put to shame, but your servant will be glad!
29 May my accusers be clothed with dishonor;may they be wrapped in their own shame as in a cloak!
30 With my mouth I will give great thanks to the Lord;I will praise him in the midst of the throng.
31 For he stands at the right hand of the needy one,to save him from those who condemn his soul to death.

I like to see the reasoning even in the poetry of the Psalms. We do not cry out to God on our own righteousness but rather because of His character, his promises, or for his reputation. Let everyone know what kind of God you are. Thehy might not get it, but those who love you do.

Let those who oppose me and therfore God look foolish.
