Thats the thing if Jesus rebuked sickness and placed his hand on people for healing then why would cancer be greater than God
You can get rid of illness with prayer but only prayer powered by the Holy Spirit for it is not by might nor by power but by my spirit sayeth the Lord.
If Jesus healed the sic and casted out devils which delivered many then we can do greater for he said greater things shall ye do in my name.
Yes God has given us the wisdom to create medicine but he has as given us power to remove it as long as we come in faith in what he said in his Word and true faith is given by the Holy Spirit.
There are many factors why people get prayed for yet still die
One of them is that they refuse to let go of the identity of the sickness some people are so wrapped up in their sickness oh do you know i Have a rare form of sickness its incurable and they said im lucky to be alive this is glorification of the sickness God does not tolerate that. This type of person would not want to let go of the sickness because they are accustomed to preach about it to everyone they know about how much nobody understands what they are going through ( do they know how much Jesus went through to die so that you could claim his healing) this leads to a closed heart and Gods power cannot flow.
another factor lets say it was not a case of healing that they needed the spirit of infirmity to be cast out they must agree to the deliverance if they do not agree no matter how much prayer is offered to cast out that spirit it wont work. Why? because that person has not agreed to be delivered and saved they have not given God permission to set them free so they spirit remains in them causing the sickness
another aspect is pride some people dont believe God is real and that he is false someone like this will find it hard to receive healing because they are fighting God within their heart with criticism God works with humility.
These are a few and there are many more but christians can receive healing and deliverance concerning sickness.
The israelites were never sick we see in the Bible up until they were enslaved in Egypt it is believed that in Egypt they learnt about medicine thus removing their trust in God as there healer and relying on the physical
many times I have prayed for God to heal me and I have been.
Many times the Holy Spirit has helped me to discern that a sickness was due to a spirit and I rebuked it in Jesus' name and the sickness left
My people perish because of lack of knowledge
If you are a christian you are powerful beyond comprehension but only when you understand the power you posses then can you use it
How do we discover that through The Word of God ( the BIble) because that is your true identity.
God even said in his Word that he is the Lord God our healer! Hallelujah
