Prayer is our armored tank. And when put into action by God’s people, “the gates of hell shall not prevail against it” (Matt. 16:18 KJV). Prayer is our major assault weapon in battle. The apostle Paul certainly used it in that manner. After listing the various pieces of equipment known as the “full armor of God” (Eph. 6:13), he mentioned prayer as being an equally essential element of spiritual warfare, just like the shield, sword, and helmet. “Pray at all times in the Spirit,” he said (v. 18).
