Mark 16:15-18 15 He said to them, “Go into all the world and preach the gospel to all creation. 16 Whoever believes and is baptized will be saved, but whoever does not believe will be condemned. 17 And these signs will accompany those who believe: In my name they will drive out demons; they will speak in new tongues; 18 they will pick up snakes with their hands; and when they drink deadly poison, it will not hurt them at all; they will place their hands on sick people, and they will get well.”
Here it says signs will accompany those who believe, signs not only accompany special people, but those who believe.
One of my high school classmates had lower back pain problem. I prayed for him, the Lord healed his lower back, the pain was gone the next day. A lady attended our church had headache problem, the headache was severe. I prayed for her from time to time. Now she has no more headache. Another person attended our church had allergic problem, his eyes were itchy. After the prayer, no more itchiness with his eyes. Thank the Lord, glory to his name.
