Our level of power or holiness has nothing to do with our ability to get ourselves or our loved ones healed.
Take the case of Peter. In Acts 3, he used the name of Jesus to get the man lying at the Temple Gate healed. In so doing, he declared that his (Peter’s) level of power or holiness had nothing to do with the healing of this helpless man. Acts 3:12, “And when Peter saw it, he answered unto the people, men of Israel, why marvel at this? Or why look so earnestly on us, as though by our own power or holiness we had made this man to walk?”
Getting your loved one healed is not dependent upon your level of power or holiness! If it was, then no one would ever be healed.
The devil will sidetrack you in this misunderstanding first. If he can make you believe that the healing of yourself or your loved one is in any way conditioned upon your own level of power or holiness, neither you nor your loved one will be healed! Why? Because not one of us, including Peter, has enough power or holiness to get any one healed. The proper approach to healing disarms the devil completely as he tries to peddle his “you are not powerful or holy enough” lie.
God alone has the power to work genuine miracles. It is up to God to decide it when and where, with whom and for whom. But it is also a truth that holiness attracts God to be present and work miracles. Repentance and humility added to faith prompts God to work miracles.
