This Sunday School lesson examines Galatians 6:17 to highlight the Apostle Paul's physical scars as evidence of his genuine commitment to the Gospel, to the Lord Jesus Christ, and to the Galatian churches. It contrasts Paul's willingness to endure persecution with the false accusations of the Galatian Judaizers who sought to pervert the truth. The lesson warns against pastors, or other church leaders, who demand absolute authority and reject biblical reproof, citing Diotrephes as a negative example of dictatorial behavior. Believers are encouraged to evaluate the character and testimony of those who lead and teach, ensuring their lives, as well as their doctrine, align with the Gospel message. Ultimately, Christians are called to stand firm in the faith, ready to face opposition, while solely glorying in Christ's cross.
