Have you ever had to speak forcefully to someone as Paul did to the Galatians (in vv8-9)? What was at stake in your case? What is at stake in the case of the Galatians? (see Gal 3:1-3).
In v6 Paul is astonished that the Galatians are “so quickly deserting the one who called you”. What does this tell us about our faith? Is it religion or relationship?
