6 Then the Lord said, “Learn a lesson from this unjust judge. 7 Even he rendered a just decision in the end. So don’t you think God will surely give justice to his chosen people who cry out to him day and night? Will he keep putting them off? 8 I tell you, he will grant justice to them quickly! But when the Son of Man returns, how many will he find on the earth who have faith?” (Luke 18:1-8 NLT)
There is a big difference between Justice and Social Justice. Justice is doing what is right. Social Justice is trying to make up for a "wrong" in the past by making someone else now pay for the "injustice."
God is a God of Justice. He will put everything right. He is also a God of Mercy. Jesus died on the cross to forgive our sins and put us right with God. God's Justice is Redemptive, Eternal. That is why we can put our trust in the Lord.
