"Now while the sun was setting, all those who had any who were sick with various diseases brought them to Him; and He was laying His hands on each one of them and healing them." - Luke 4:4
This writing is dealing with some Christians thinking instantaneous, miraculous healing should be the norm - and that something is wrong with us if it isn't.
Sometimes God heals instantaneously. Sometimes God allows healing to take time - to happen gradually. Sometimes healing is accomplished through physical death. (Death and going to heaven is a beautiful healing. We are fully restored and healed in Paradise. [When praying and believing for instantaneous healing, we need to be asking God if this sickness or infirmity is"unto death" - and be okay if it is. We say we believe heaven is a better place.])
New Testament Christians and others experience(d) both quick healing and recovering healing - healing that took time. Most of us will probably die from some kind of physical sickness, disease, or condition that God chooses not to heal.
"These signs will accompany those who have believed: in My name they will cast out demons, they will speak with new tongues. . . they will lay hands on the sick, and they will recover.” - Mark 16 It says they will recover. It does not say instantaneously healed.
The church elders were to pray for the sick when they were called upon to do so - and through the laying on of hands / praying over the person, and with the anointing of oil, the prayer of faith would "restore the one who was sick." - James 5 It says "will restore." It does not say instantaneously be healed.
Sometimes God allows someone the strength to bear a sickness or debilitation (The Apostle Paul's thorn in the flesh. - 2 Cor 12) . . . God allows stuff. This can be unnerving.
God also disciplines His children if he needs to - with protracted healing. . . or better said, allows and even sends sickness and infirmity - as a tool of discipline - even for his own children!
The Lord Jesus surely threatened the so-called prophetess Jezebel and some of His own bond-servants in the Church of Thyatira with sickness, disease, and even death. A number of Christians believe that God would never do something like that. That all sickness and evil is from the devil, and God would never have any part of it. They do not know Him as well as they need to. Jesus said Himself,
"I gave her time to repent, and she does not want to repent of her immorality. Behold, I will throw her on a bed of sickness, and those who commit adultery with her into great tribulation [these were some He called "My bondservants"], unless they repent of her deeds. And I will kill her children with pestilence." - Rev 2 Did He say, children? By pestilence?
This is God - who is to be feared. Jesus said, "But I warn you whom to fear: fear the One who, after He has killed someone, has the power to throw that person into hell: yes, I tell you, fear Him!" - Luke 12:5
This is one reason we need to strive to stay spiritually clean and "right" before God, and if we do get sick or get a disease - make sure it is not a consequence of our own doing. Jesus told the paralyzed man whom He had just recently healed, “Behold, you have become well; do not sin anymore, so that nothing worse happens to you.” - John 5:14
Sometimes God chooses to prolong our healing to test us and to see what we really have in our hearts. It seemed Job was tested to such an unnerving, long, and painful degree . . . that ultimately Job started to question if God was a good God or not. He seemed to begin to manifest or infer or accuse God of not being a Good & Righteous & Fair God.
If we do not even understand the fringes of how the physical world works ("Where were you when I laid the earth's foundations? , etc.") . . . (It seems God was telling Job this.) . . . Who are we (or Job) to question or understand the magnificent and unfathomable processes of how God works in the hearts of men? . . . How He molds and changes the human hearts of His Beloved!?
There is comfort for us in Job's long & painful tribulations. God is God, and knows what He is doing. . . .and He allows pains, sicknesses, pestilences - on His loved ones - for good reasons and good intentions. Job ended-up being and becoming a better man. Potentially very frightening, very unnerving stuff, however.
No matter what happens to us - let us always predetermine and determine and remind ourselves that we will always believe in God and be confessing to God that He is a Good and Trustworthy God, and that we love and trust Him - NO MATTER WHAT HAPPENS !
In one sense - we really deserve anything bad that ever does happen to us! . . . We deserved to go to Hell !
