God forbids injustice. It's in the Bible, Deuteronomy 16:19, NIV. "Do not pervert justice or show partiality. Do not accept a bribe, for a bribe blinds the eyes of the wise and twists the words of the righteous."
God is tired of our injustice. It's in the Bible, Habakkuk 1:3, NIV. "Why do You make me look at injustice? Why do You tolerate wrong? Destruction and violence are before me; there is strife, and conflict abounds."
Overcome evil injustice with good. It's in the Bible, Romans 12:21, TLB. "Don't let evil get the upper hand but conquer evil by doing good."
