I must confess I am never sure whither God will heal a person or not, I was at a friends recently. He spoke of a man who was not a Christian ,and how his daughter prayed for him and God healed his cancer.He mentioned other
incidences ,of people being healed,in the church in which I was a minister,
two of my members told of healing's ,one was very badly scalded ,she was prayed for,the other told of her father being healed of cancer.Now I have mentioned it before my first wife died of cancer,I did pray,but she died,so you see how I am not sure whither God will heal a person or not. God can heal,but may not,but he may,Paul's experience,is an example of this [2 Corinthians 12].Jesus healed many but he did not choose to heal everybody,
we must not think that He has to.Recently while visiting a Christian lady,
she told me that she had cancer,a severe type,it had a high number ,that indicated ,that was very bad.That evening I read James 5 v14-15 ]which tells us to call for the elders anoint the person with oil,and pray in faith,and the person would get well.This was done,she did not become well at that time,but the treatment she is having,appears to be dealing with the cancer.
Dear God we know that with you,nothing is impossible,help us not rule out
your healing power,in Jesus name Amen.
