"Christianity today is man-centered, not God-centered." (No doubt!)
"The old cross is a symbol of death. It stands for the abrupt, violent end of a human being."
"The whole world has been booby-trapped by the devil, and the deadliest trap of all is the religious one."
One of the things I appreciate most about Tozer is that he was highly critical of the modern evangelical church and yet was himself a modern evangelical. I think he saw the many ways that the church was selling out to partisan politics and worldly concerns (e.g. this prosperity gospel nonsense) and departing from the actual texts of the Gospel.
I like him very much when he criticizes the church (and the Western world) and talks about God, less so when he criticizes the world (almost to the point where he seems a smidge isolationist; I don't recall very much in Tozer about the great commission) and even less so when he seems to suggest that wrestling with faith or trying to make intellect part your belief is, in fact, a form of unbelief. Some of this might be the culture and time and social climate he was writing in. That being said, I highlighted 70 different passages of this little book. You're going along and then BAM, Tozer lays a brilliant insight out and you're like, 'Daggone. That dude's deep.'
