In this study, we discuss Paul's defence against those who sought to sow discontent. Paul's defence was grounded in his genuine actions, urging the Thessalonians to scrutinize his preaching, motives, and conduct. He emphasized his willingness to suffer for the Gospel, the consistency and purity of his message, his focus on pleasing God over people, his gentle and generous demeanour, and his sincere exhortations to live for God.
