From the very beginning of creation we understand Justice because it flows from the character and nature of God our creator. All humanity is created in His image and thus are intended to be treated with honour and respect. How we treat each other is about enacting that Justice. The church does better in reactive justice than we do with proactive justice. We are being called to seek out where there is systemic injustice and bring the Gospel of Jesus to bear in practical ways - seeking to deal with not only the "ripple" but the "rock" that caused it in the first place.
