Are you ill? Begin to rejoice in the Lord, and your bones will flourish like an herb, and your cheeks will glow with the bloom of health and freshness. Worry, fear, distrust, care-all are poisonous but joy is balm and healing, and if you will but rejoice, God will give power.
He has commanded you to be glad and rejoice, and He never fails to sustain His children in keeping His commandments. Rejoice in the Lord always, He says. This means no matter how sad, how tempted, how sick, how suffering you are, rejoice in the Lord just where you are-and begin this moment. The joy of the Lord is the strength of our body.
A cheerful heart is good medicine, but a broken spirit saps a person's strength.
