When Jesus was on this earth, He never told anyone who needed healing to go and get help. Instead, He healed them. What the pastor is going through is a work of the devil, and Jesus gave us power over all the works of the devil.
Luke 10:19King James Version (KJV)
19 Behold, I give unto you power to tread on serpents and scorpions, and over all the power of the enemy: and nothing shall by any means hurt you.
When Jesus sent His apostles out amongst the sick He did not command them to tell the sick people to go and get help. Instead, Jesus told them to heal the sick, cleanse the lepers and raise the dead, and cast out devils. Believers can do the same works that Jesus did, and is not limited to just the apostles.
John 14:12King James Version (KJV)
12 Verily, verily, I say unto you, He that believeth on me, the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father.
James gave the church a solution for healing.
James 5:14-16King James Version (KJV)
14 Is any sick among you? let him call for the elders of the church; and let them pray over him, anointing him with oil in the name of the Lord:
15 And the prayer of faith shall save the sick, and the Lord shall raise him up; and if he have committed sins, they shall be forgiven him.
That prayer of faith is a believing and having faith that God wants people well and the elders are doing what the Bible commands us to do. Jesus and the Holy Spirit are working through people these day. There is power in the name of Jesus. Jesus gave us permission to use His name.
The woman with the issue of blood had been to lots of "doctors" to get well, and none could help. Her faith in the healing power of Jesus was expressed and as she touched the hem of Jesus garment, she was healed.
The church these days is falling far short of the expectations of Jesus, and His apostles, and the early believers.
Romans 8:11New Living Translation (NLT)
11 The Spirit of God, who raised Jesus from the dead, lives in you. And just as God raised Christ Jesus from the dead, he will give life to your mortal bodies by this same Spirit living within you.
The church needs to become believers again.
In the name of Jesus, I bless you with the life of God and His wisdom and understanding.
