Choosing Electives

I've heard discussion before on wether or not certain church activities help promote the church, and wether the church can, or should indorse them. For example, does having an official church baseball team further God's kingdom? Or if the church takes a group to go see a rated R movie does that reflect well on the church or Christians in general? Although I find these discussions somewhat pointless I've wondered lately why we dont ask these questions of our everyday lives. When we rail on about saving the earth, and fight with people who don't agree are we furthering God's kingdom? Does the fact that I've taken up brewing allow me more ministry oppurtunities? Is it my activities, or my actions that will allow me to live a life above reproach?
