Justice only becomes justice if it is enacted in a specific instance.
Therefore, if justice remains a concept it becomes injustice.

Do I bring justice or do I just want it to happen?
If I just want it to happen without doing what it takes to make it happen in the life I walk through every day, do I really want it?

I'm looking at my schedule for today.
Justice has not made the list.

If you and I put pursuits of justice on our lists then the people as numerous as the sands can change.  If you move the sand the dry desert changes.  If you change the desert you change the world.
