Body

Infectious germs cause disease. Satanic oppression can also cause pains in the body. The illness of Job, the just man, was a result of satanic attack. Many diseases are cured by medicine. The Bible advises not to belittle the doctor and the medicine. "And he gave skill to human beings that he might be glorified in his marvellous works. By them the physician heals and takes away pain, the pharmacist makes a mixture from them." (Sirach 38: 6-7) Then give the physician his place, for the Lord created him; do not let him leave you, for you need him. There may come a time when recovery lies in the hands of physicians." (Sirach 38: 12-13) There are certain diseases that cannot be cured by medical science. Prayer may heal us of such diseases. Jesus Christ heals even the fatally and critically sick.
"Now there was a woman who had been suffering from haemorrhages for twelve years. She had endured much under many physicians, and had spent all that she had; and she was no better but rather grew worse. She had heard about Jesus, and came up behind him in the crowd and touched his cloak, for she said, 'If I but touch his clothes, I will be made well.' Immediately her haemorrhage stopped; and she felt in her body that she was healed of her disease." (Mark 5:25-29)
Jesus healed the man who had been paralysed for 38 years. Bethsaida was a sacred place. Many sick people got cured of their illness. Jesus healed the one who was there unhealed. "Jesus said to him, 'Stand up, take your mat and walk'. At once the man was made well, and he took up his mat and began to walk." (John 5:8-9)
The Bible says: "My child, when you are ill, do not delay, but pray to the Lord, and he will heal you. Give up your faults and direct your hands rightly, and cleanse your heart from all sin." (Sirach 38:9) It is not easy for one who is in sin to be healed. "He who sins against his Maker may fall into the hands of the physician." (Sirach 38:15; alternate rendering) The Bible says, if we do not repent after committing a sin, it will lead us to sickness. If we confess our sins and get delivered from sin, we will not get sick as a result of sin.
"When Jesus saw their faith, he said to the paralytic, 'Son, your sins are forgiven ... I say to you, stand up, take your mat and go to your home.' And he stood up, and immediately took the mat and went out before all of them." (Mark 2:5;11-12) Jesus understood that this man was sick not because of germs; but because of sins. Jesus forgave his sins first. Then he got healed. "Pray to the Lord, and he will heal you." (Sirach 38:9)
"In those days Hezekiah became sick and was at the point of death. The prophet Isaiah son of Amos came to him and said to him 'thus says the Lord: Set your house in order, for you shall die; you shall not recover.' Then Hezekiah turned his face to the wall, and prayed to the Lord: "Remember now, O Lord, I implore you, how I have walked before you in faithfulness with a whole heart, and have done what is good in your sight." And Hezekiah wept bitterly. Then the word of the Lord came to Isaiah: " Go and say to Hezekiah, Thus says the Lord, the God of your ancestor David: I have heard your prayer, I have seen your tears; I will add fifteen years to your life. I will deliver you and this city out of the hand of the king of Assyria and defend this city." (Isaiah 38: 1-6)
