How the Supremacy of Christ Creates Radical Christian Sacrifice

I've listened to this sermon many, many times.

I'm prone to getting 'off-message' in my life. Little things (money, school, grades, work, football, etc.) often fight their way to the front of my mind and heart, and the Big Thing (the Kingdom) becomes peripheral. God regularly uses the sermons of John Piper, a Baptist pastor up in Minnesota, to re-focus me.
