I tried to track these down by location, but it proved surprisingly difficult. I eventually gave up and just picked the most beautiful ones.
Never give up, there’s a rainbow bending
Over the path so dark and steep,
And all of the rain that God is sending
Is for harvests of love you shall some day reap.
Never give up, there’s a blessing hidden
Deep in the heart of every woe,
Some happy day it will rise unbidden
As the crocus blooms after winter snow.
Never give up, there’s a bright star shining
Somewhere in the depths of the darkest night,
And the darkest clouds show their silver lining
When hope returns with the morning light.
