I found these four questions quite helpful in thinking about ways to engage and serve my community. Why not get together with other concerned Christians and wrestle with the questions? Be ready for what the Lord will show you and call you to do.
First, what is good in our culture that we can promote, protect, and celebrate?
Second, what is missing in our culture that we can creatively contribute?
Third, what is evil in our culture that we can stop?
And finally, what is broken in our culture that we can restore?
