I have been praying for 2 specific people who have been struggling with cancer. They are now cancer-free and everything that had been associated with their cancer has gone. Both of these people were unsaved. Now they have accepted Jesus as their personal Lord and savior. He is the same yesterday, today and forever. Jesus Christ's redeeming work on the cross continues to save and heal people when we pray and ask him by faith in his mighty name. Glory!
