Well there is some sin that will get a women cast into the sick bed.
Woah, hold on a minute.
This is a generalisation, is not Scriptural and I don't think is fair.
If God has
revealed to someone - healer or sufferer - that the cause of illness is a specific sin, then of course that needs dealing with, and when it has been, then healing will come. Sin CAN be the cause of a specific illness - but it is also very possible that someone might be sick simply because we live in a fallen, imperfect world.
It can't be the case that sin leads to sickness and all sickness is healed by repentance, otherwise ALL non Christians, unrepentant criminals and so on would be terminally ill, and all Christians would be in perfect health, or restored to perfect health after confession.
In John chapter 9 Jesus was questionned on this very point, in fact; the disciples said, "who sinned - this man or his parents?" Jesus' answer was "no one".
I know from experience that implying that a person with a chronic illness is that way because of sin, is not nice, is hurtful and causes the person to put their eyes on themselves, ("what have
I done? Why am
I so bad? etc) rather than on God. It can also burden the sufferer with feelings of guilt, worthlessness and condemnation - and they/we don't need that on top of struggles with physical symptoms.
Is she manipulative, controlling and in rebellion against a husband's authority? Is she arrogant believing her ways are superior? Is she self-righteous? Is she a meddlesome busybody in the matters of other people's lives? Does she punish others that don't do as she wishes even though they are not under her authority? Does she pray prayers of imposing her will onto other people's lives? Does she use bribery or barter or seduction to get what she wants? Does she use gossip to punish? Those attributes will get a women cast into a sick bed until she repents.
Again, that is a generalisation, not true and rather judgemental. It is for God to reveal the cause - if there is one - of a sickness; not for us to speculate.
I have seen many Jezebels cast into the sick bed. I understand the full range of attributes associated with that error. I knew a high priestess of Ashtoreth many years ago. I have seen women that had a subset of her attributes cast into the sick bed many times. One of my sister-in-laws died of it. She refused to repent or even admit error up until the end.
And I have heard of many non Christians, cult members and so on; people who either try to live a good life without God or who openly reject or defy him who are perfectly healthy - while world famous evangelists like David Watson have died of cancer.
You and your wife need to do some serious self-examination. She won't get healing unless she roots out the cause. Something opened the door to the attack. Speaking it away with WoF doctrine is pointless if the root cause is not dealt with. The roots of bitterness have to be dealt with.
NO.
The forummer in question, and his wife, need to be reassured that God loves them both very much; that sickness is not a punishment for sin, Jesus paid the price for their sin on the cross; that NOTHING can ever separate them from God's love; that they are accepted by God, adopted as his children and belong to him. I believe that the the Lord wants everyone to be whole; saved, healed and physically well. I believe also that he knows what they are going through physically, can deal with their hurt, confusion, maybe even anger, and wants them to be able to express that to him so that their relationship might be even deeper.
If they, or anyone else, were to ask God directly if a sickness has a specific cause or is due to a certain event, then I am certain that God would reveal that to them. But equally, he might say nothing on the subject, and in that case it would be wrong to teach, or assume, that they are sick because they sinned.
