Luther on preaching

I came across this excellent quote this morning from Martin Luther on the primary role of preaching the Word within the church:
" Now wherever you hear or see the word preached, believed, professed, and lived, do not doubt that the true ecclesia sancta catholica (Christian, holy people) must be there.... and if no other sign than this alone, it would still suffice to prove that a Christian holy people must exist there, For God's Word cannot be without God's people and, conversely, God's people cannot be without God's Word.
As quoted by Al Mohler in a Feed My Sheep, A Passionate Plea for Preaching. p.1 (looks like its going to be a fantastic read)
Shalom
