Here's a great application point from Colossians 1 from Wright's.
"The task... is therefore best understood as the proclamation that Jesus is already Lord, that in him God's new creation has broken into history, and that all people are therefore summoned to submit to him in love, worship and obedience. The logic of this message requires that those who announce it should be seeking to bring Christ's Lordships to bear on every area of human and worldly existence. Christians must work to help create conditions in which human beings, and the whole created world, can live as God always intended. There is a whole range of ethical norms which God built into his world: a respect for persons and property, maintenance of family life and of the ecological order of creation, justice between individuals and groups. Christians must be in the forefront of those working to promote such causes. Many opportunities to speak about Jesus will occur in the undertaking of such work, as it becomes clear that the gospel provides a coherent and satisfying underpinning for those standards which uphold and enhance a truly human life."
