Curiously, the righteous Pharisees had little historical impact, save for a brief time in a remote corner of the Roman Empire. But Jesus' disciples - an ornery, undependable, and hopelessly flawed group of men - became drunk with the power of a gospel that offered free forgiveness to the worst sinners and traitors. Those men managed to change the world.

The world is not against you, but the world is a place where bad things happen. It's just true. Airlines crash, people do evil things. A lot of bad things happen and it causes pain.

Christians have an important role to play in contending that no human life is "devoid of value." We can do so through courageous protest, as happened in Germany, as well, as in compassionate care for the most vulnerable members of society, as Mother Teresa did. In both approaches theology - what one believes about God and human life - matters. The world desperately needs that good news.

Be salt, and a little bit of salt keeps the whole society from going rancid.

The world thirsts for grace. When grace descends, the world falls silent before it.

Politics deals with externals: borders, wealth, crimes. Authentic forgiveness deals with the evil in a persons heart, something for which politics has no cure. Virulent evil (racism, ethnic hatred) spreads through society like an airborne disease, one cough infects a whole busload. When moments of grace do occur, the world must pause, fall silent, and acknowledge that indeed forgiveness offers a kind of cure. There will be no escape from wars, from hunger, from misery, from rancid discrimination, from denial of human rights, if our hearts aren't changed.

Our best efforts at changing society will fall short unless the church can teach the world how to love.
