The Lord healed the prostate cancer of my father in law

A few years ago, My father in law got prostate cancer, the cancer cells were spread, he could not walk properly, he was admitted to the hospital. One of my wife’s relative is a preacher, he went to the hospital to pray for my father in law, after prayer, my father in law was healed by the LORD and he left the hospital, he could walked properly again. He is over 80 years old now,  he is still in good shape physically.  He became a christian when he was young. Praise the LORD.
