4 things

1) As long as we think that 'success' is the same as 'popularity', we will fail.
2) As soon as we forget the cross and what it means, we will make Jesus (and Christianity, for that matter) a means to our own ends.
3) We will think that 'being in positions of influence' will be the only way for real change when we forget who Jesus was.
4) Most of us read the Bible thinly and without a proper understanding of the context from which Jesus comes from and into which Jesus speaks. Therefore we fail to see the counter-cultural (read: subversive) nature of the Gospel, of Jesus, and of Paul (and the whole Bible, really). If this is the case, we will always be 'chaplains to power' and affirm the status quo.
