Proverbs 17:22

A merry heart doeth good like a medicine: but a broken spirit drieth the bones.

The devil will attack our spirits by attacking our bodies.  He sends sickness to make us question whether Jesus died for our sins and sicknesses. The devil wants us to get down and depressed.  Laugh at him and praise God, and thank God for your healing. Let our hearts be merry because we have the answer in Jesus.   If we need to take medicine praise and thank God for our healing as we take the pills and remind the devil that the healing is ours.
