Jar.

I found a little joy
So I put it in a jar
Then I put the jar away
Just to keep my joy from harm
When I put the jar away
It was a place inside my heart
I so wanted my joy safe
So I set it far apart

But when the clouds all move
And the sun is setting right
And you feel the love of God
Shining really all too bright
When there are people that you love
Just within your very sight
Then sometimes your joy explodes
From the jar you kept inside
