“It happened on one of them zip-a-dee-doo-dah days. Now that’s the kind of day where you can’t open your mouth without a song jumping right out of it!”

Not every day is a “feel good day”, but some days that may not start there have the potential to move there.
Have you ever thought about preaching to your soul about singing to your soul?
Praise the Lord, my soul; all my inmost being, praise his holy name. Praise the Lord, my soul, and forget not all his benefits— who forgives all your sins and heals all your diseases, who redeems your life from the pit and crowns you with love and compassion, who satisfies your desires with good things so that your youth is renewed like the eagle’s. (Psalms 103:1-5)
