Do you want to be of the kingdom of Christ?

I’ve been studying today for preaching on Sunday and I came across this passage that made me sit up and think.

The desperate need for Christians to excise innumerable church meetings, in order to free their diaries for proper meeting with unbelievers, was summed up with characteristic candour and pungency by Martin Luther: “The kingdom is to be in the midst of your enemies. And he who will not accept this does not want to be of the kingdom of Christ. He wants to be amongst friends, to sit among roses and lilies, not with the bad people. Oh, you blasphemers and betrayers of Christ! If Christ had done what you are doing, who would ever have been spared?”

Prior, D. The Message of 1 Corinthians, p 83.
