Most of the time, if you want to confront someone, you start with some good news first. A compliment or an affirmation of your relationship to them might precede the hard conversation. Paul often commends the churches he writes to for things he knows they are doing well. In Galatians, Paul moves directly from the brief reminder of the gospel message to the bad news: in listening to the message of the Judaizers, the Galatians have turned away from the gospel entirely! Paul responds with alarm to the spiritual threat that the Galatians don’t see, in the same way that we would if we saw a friend stepping out into oncoming traffic. No time for pleasantries!
