The devil is the one ruling the world today. He causes the diseases and the sicknesses in this world.
Jesus cast out devils from many of the people that He healed.
So many problems are caused by the devil. Until you get to the root of the problem you often do not get them solved.
This is why Jesus is in the healing business. This is why we believe in healing. We can never stop believing in healing.
I want to encourage you to believe in miracles because miracles are real.
Jesus is the Sun of righteousness with healing in His wings.
