What does the bible say about injustice?

How do I approach injustice through the lens of the bible?

Dearest Jesus, I am hurting for my world and being black is a privilege and not a curse. Psalm 139:14 is a perfect description of what God sees when he looks at you as a human being. God did a good job when he formed you in your mother's Womb. Black, white, Indian, Asian, Hispanic. We all add up to make the combination to the safe of God's heart(Woah that just blew my mind). Injustice is bad and it takes away from the completeness that God had in mind. Let me know your testimony, God knows you and loves you.
