There was a song on the old Flintstones cartoon (produced by Hanna-Barbera) where Pebbles and Bamm Bamm sang a song called "Let the Sunshine In" … I suggest you Google it, it will really put a smile on your face. Highly recommend tracking down the original if you've never experienced it before!
Part of the lyrics:
"Mommy told me something
A little kid should know
It's all about the devil
And I've learned to hate him so
She said he causes trouble
When you let him in the room,
He will never ever leave you
If your heart is filled with gloom"
"So let the sun shine in
Face it with a grin
Smilers never lose
And frowners never win
So let the sun shine in
Face it with a grin
Open up your heart and let the sun shine in"
It's a spiritual battle.
Smile … God loves you!
