Paul knew that the Thessalonians would face pressure from persecutions, false teachers, worldliness, and apathy to waver from the truth and to leave the faith.
So he urged them to “stand firm” and hold on to the truth they had been taught through both his letters and in person. We also may face persecution, false teachings, worldliness, and apathy. We should hold on to the truth of Christ’s teachings because our lives depend on it. Never forget the reality of Christ’s life and love!
With all these things in mind, dear brothers and sisters, stand firm and keep a strong grip on the teaching we passed on to you both in person and by letter.
