Since we are physical and spiritual beings, worry can negatively effect both.
Something must change in the spiritual before it effects the physical.
Worry is a manifestation of not having faith in the midst of difficulty and hardship.
The answer is Jesus Christ will bring peace that supasses understanding when life can look perilous.
Yet I will rejoice in the LORD, I will joy in the God of my salvation. - Habbakuk 3:18
