Galatians 4-12 marks a change in Paul's tone, and Galatians 4-12-20-include the most warm and personal words of this letter. Paul is no-longer writing as a scholar or a theologian. Paul is no longer-presenting arguments as an apostle. Paul is no longer charging the-Galatians or condemning them for their wrong. Paul is making a-heartfelt appeal to them as his friends.
