Only let your behavior be worthy of the Gospel of Christ, so that, whether I return and see you, or whether, being absent, I hear about you, still you may stand firm with one spirit, with one mind, laboring together for the faith of the Gospel.
Therefore, keep in mind the way that you have received and heard, and then observe it and repent. But if you will not be vigilant, I will come to you like a thief, and you will not know at what hour I will come to you.
