First of all, just because you can’t do everything, it doesn’t mean you should do nothing at all. There’s a sort of a sense (that says), “I can’t solve the problem of world poverty and inequality, so I won’t do anything.” Do what you can. Not what you can’t. That comes out of prayer. So for a local church community, pray. Start with prayer about your local community. Contemplate, listen in silence. Allow the spirit of God to speak, and look and see what happens.
Secondly, be outward looking and engaged and take risks. Take risks, but risks that are based out of a life of prayer in your community. We are based in a relationship of love for Jesus Christ, so start with what we know and see what he calls us to do.
