Withstand him steadfast in your faith, knowing that your brothers who are in the world are undergoing the same sufferings.
      III. He tells them that their care was not singular, for they knew that the like afflictions befel their brethren in all parts of the world, and that all the people of God were their fellow-soldiers in this warfare. Learn, 1. All the great persecutions that ever were in the world were raised, spirited up, and conducted, by the devil; he is the grand persecutor, as well as the deceiver and accuser, of the brethren; men are his willing spiteful instruments, but he is the chief adversary that wars against Christ and his people, Genesis 3:15; Revelation 12:12. 2. The design of Satan in raising persecutions against the faithful servants of God is to bring them to apostasy, by reason of their sufferings, and so to destroy their souls. 3. Sobriety and watchfulness are necessary virtues at all times, but especially in times of suffering and persecution. "You must moderate your affection to worldly things, or else Satan will soon overcome you." 4. "If you would overcome Satan, as a tempter, an accuser, or a persecutor, you must resist him stedfast in the faith; if your faith give way, you are gone; therefore, above all, take the shield of faith," Ephesians 6:16. 5. The consideration of what others suffer is proper to encourage us to bear our own share in any affliction: The same afflictions are accomplished in your brethren.
