Note 10 at Gal. 6:18: This letter to the Galatians was a harsh letter (see INTRODUCTION TO THE EPISTLE OF PAUL TO THE GALATIANS, p. 1050) and Paul's previous sentence stated that his terms were only 100 percent surrender on their part. Yet, he closes with a blessing of the grace of Jesus over his brethren. It was love that compelled Paul to be stern (see note 9 at Gal. 4:16, p. 1074).
