But does it deal with sin?

Kingdom redemption, then, is the work of God, through Jesus, and by virtue of his sin-solving cross and new-life-creating resurrection, unleashed to those who are needy because of their sins. Any kind of “redemptive” activity that does not deal with sin, that does not find its strength in the cross, that does not see the primary agent as Jesus, and that does not see it all as God’s new creation life unleashed is not kingdom redemption, even if it is liberating and good and for the common good.— Kingdom Conspiracy, page 150

Indeed! As far as I'm concerned, that's the distinguishing mark between "Christian" works and "good" works. If it doesn't deal with the core issue of sin, then it might be very good, but it isn't a distinctly Christian work. It can be done by Christians—and there should be more Christians doing this kind of thing—but it isn't distinctly Christian.
