The human spirit can endure in sickness,
but a crushed spirit who can bear?
(Proverbs 18:14)

It's difficult to be sick.  None of us like to be sick, but it's pretty inevitable that we will all be sick at one point or another.  When we do face illness, if we turn to God for support, hope, and strength, it eases our suffering, whether it takes away the illness or not.  On the other hand, if our spirit is ill, what hope do we have?
