"Is this not the fast that I want: Free those who are wrongly imprisoned; lighten the burden of those who work for you. Let the oppressed go free and remove the chains that bind people. Share your food with the Hungry and give shelter to the homeless. Give clothes to those who need them and do not hide from those who need your help - Isa 58:6-7"
What God requires from us is so straight-forward.
Believe me, when you start asking "to see Justice flow like a mighty River", you are reaching out to the Fathers heart and I have experienced this and the truth is that His Heart moves for "Justice", "Righteousness" and "Freedom".
OK, Spend some time this week praying for "Injustice"/"Poverty" and the likes. Ask God to give you a heart for the things that cause his heart to beat and just see him move in you and through you to the people around you.
