Then why did Jesus say to those He healed, “you faith has made you whole”? In almost every case of healing, He referred to the person’s belief or faith. The woman with the issue of blood is one example, Mark 5. The man whose son was a lunatic is another, Matthew 17.
Brother Hagin taught that when the gift of healing was in operation, and when the anointing for healing was on him to heal, everyone got healed, even those that didn’t have faith for it.
He also said that a lot of people don’t keep their healing; one of the reasons he gave is because if they feel symptoms of what they were healed occur, they’ll negate the healing they received by their words of unbelief, thereby causing the illness to return because of the words of unbelief they spoke. (Proverbs 18:20)
Jesus told the man from the pool of Bethesda to not “sin anymore lest a worst thing come upon him.” So we know that sickness can return even after healing takes place. John 5:14
Jesus was anointed by the Holy Spirit, and I believe the anointing was upon Him every time He healed people...That is not always the case when we lay hands on sick people.
“...how God anointed Jesus of Nazareth with the Holy Spirit and with power, who went about doing good and healing all who were oppressed by the devil, for God was with Him.” **Acts *10:38 *
