It's already years ago that I read some books by A.W. Tozer. It's amazing how relevant this fiery preacher still is, as the western church is still suffering from a self-inflicted Laodicea complex. A quote from chapter 7 of 'This World: Playground or Battleground?':
"The most critical need of the church at this moment is men - the right kind of men, bold men. The talk is that we need revival, that we need a new baptism of the Holy Spirit - and God knows we must have both - but God will not revive mice. He will not fill rabbits with the Holy Spirit. We languish for free men, who are not forced to do things by the squeeze of circumstances. Their only compulsion will come from within - or from above. This kind of freedom is necessary if we are to have prophets in our pulpits again instead of mascots. The free man has nothing to protect, no ambition to pursue and no enemy to fear. He is made of the stuff of which martyrs are made. He will have God on his side because he is careful to stay on God's side."
