My desire and prayer to God is that your life and your ministry would have a radical flavor; a risk-taking flavor; a gutsy, counter-cultural, wartime flavor – that makes average American people in your church uncomfortable; a strange mixture of tenderness and toughness that keeps people a little bit off balance; a pervasive summons to something more, something hazardous, something wonderful; a saltiness and a brightness about your life and your church; something like Jesus; some extraordinary love, something risky, some crazy sacrifice that nobody can understand - including mom.
-John Piper [T4G sermon]
