The Cowboy Church Sunday School Miscellaneous Open Up Your Heart (and Let The Sunshine In) OPEN UP YOUR HEART The Cowboy Church Sunday School My mommy told me something a little girl should know It's all about the devil and I've learned to hate him so She says 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. When you are unhappy the devil wears a grin But oh, he starts a running when the light comes pouring in I know he'll be unhappy cause I'll never wear a frown Maybe if we keep on smiling he'll get tired of hanging around.
