Someone has said that worldliness is living in a committed way to the wrong principles. The people of God--Israel, the church--is a contrast to the world: it is the world organized on right principles. And those right principles involve, as Jesus makes so clear in the Lukan kingdom thread, justice and peace and love of others. A thoroughly biblical understanding of atonement, then, is earthy. It is about restored relations with God and with self, but also with others and with the world--in the here and now.
So Paul took his stand in the open space at the Areopagus and laid it out for them: "I'm here to introduce you to this God.... He doesn't play hide-and-seek with us. He's not remote; he's near. We live and move in him, can't get away from him!" ~Acts 17
