Ask the Pittsburgh Steelers, Pirates, or Penguins: to be effective to accomplish your mission, the whole team has to step up. How effective would the Steelers be, for example, if Big Ben was the only one who ever showed up to play?
In the same way (actually much more so!), God's Spirit empowers ALL believers for the benefit of the team - the church! (1 Corinthians 12:7). Don't be a benchwarmer. Come and see how God's power is to be manifest through you... for the team!
