If you are trying to live a life in accordance with the Bible, the concept and call to justice are inescapable. We do justice when we give all human beings their due as creations of God. Doing justice includes not only the righting of wrongs but generosity and social concern, especially toward the poor and vulnerable.
Timothy KellerThe sin that is most destructive in your life right now is the one you are most defensive about.
Timothy KellerA church must be more deeply and practically committed to deeds of compassion and social justice than traditional liberal churches and more deeply and practically committed to evangelism and conversion than traditional fundamentalist churches. This kind of church is profoundly counter-intuitive to American observers. It breaks their ability to categorize (and dismiss) it as liberal or conservative. Only this kind of church has any chance in the non-Christian west.
Timothy Keller[T]he main problem in life is sin, and the only solution is God and his grace. The alternative to this view is to identify something besides sin as the main problem with the world and something besides God as the main remedy. That demonizes something that is not completely bad, and makes an idol out of something that cannot be the ultimate good.
