I came across this one over at The Pastor’s Toolbox, a great enewsletter put out by Pastors.com.
"Often people feel the church exists to take care of problems. And it’s terribly hard for the church to say no. And yet the effective ones say no. They know what their mission is, and they make no apologies for sticking to that." – Peter Drucker, in a 1989 Leadership magazine interview
Do you know what your mission is?
