In the bible it talks about so many instances in the gospel about healing the sick. And in Psalm 103 it says to not forget His benefits, for He heals all your diseases and forgives all your iniquities. So He does! So if you ever see someone who needs help in that or a healing you can pray, you can lay hands on the sick and heal them.
And if you yourself have not experienced this ever, be encouraged to know it is possible.
