If you have not seen any miraculous healings, you are not alone. Does this mean that God does not heal people today? No, not at all. Unfortunately, many Christians believe a lot of things that are not in the Bible. Many people depend on their own logic, tradition, or experience to formulate their beliefs. Few accept the Word of God only for their beliefs. The result is Mark 7:13 "Making the word of God of none effect through your tradition, which ye have delivered: and many such like things do ye."
They are living in the sense realm and not by faith. They could be following church traditions that deny miracles and therefore they don't go where miracles take place. We do run into this situation occasionally in the healing rooms. In June, 2016, we had a couple come in for healing. The wife had seen miracles before and the husband had not. Because of this he was not initially receptive to prayer and it took some discussion before he was even interested in prayer, even after he saw his wife healed of a broken foot. He was trying to be stoic about his situation. He said that he almost bolted because of a religious spirit but he didn't because his wife was there, and we were able to pray for him, and his back problems were healed. They left with the wife walking in her regular shoes and the husband carrying the crutches. As a side note, she had enough faith to bring along her regular shoes while coming to the healing rooms on crutches with her special shoe on for a broken foot.
