Roughly 1 in 15 verses in the Bible (approximately 2,100) talk of the concern God and His people have about injustice, poverty, and oppression.  These issues come up a lot.  The Bible is trying to tell us something.

Our faith has a lot to offer people about living and loving well, choosing purposefully, acting meaningfully, and sharing hope. 

This book is a kind of stepping-stone.  It might help you see with new eyes and to hear with new ears the cries of the oppressed.  It might encourage you to engage in new ways with compassion in the world around you or even somewhere on the other side of the world.  Or, it might just build your compassion and encourage you to pray for the suffering of others.

Injustice is not overwhelming and it is not immovable.

For I was hungry and you gave Me food; I was thirsty and you gave Me drink; I was a stranger and you took Me in; I was naked and you clothed Me; I was sick and you visited Me; I was in prison and you came to Me.
Then the righteous will answer Him, saying, ‘Lord, when did we see You hungry and feed You, or thirsty and give You drink? When did we see You a stranger and take You in, or naked and clothe You? Or when did we see You sick, or in prison, and come to You?’ And the King will answer and say to them, ‘Assuredly, I say to you, inasmuch as you did it to one of the least of these My brethren, you did it to Me.’– Matthew 25:35-40 NKJV
