happiness -christian movie from the early 80s late 70s

hi, i am looking for a movie called happiness. it is a christian movie from the early 80s, maybe even the late 70s.. the main characters are 4 kids, 3 boys and a girl that go to church/bible study together. the boys dont want to play with the girl but tell her she can be in their club if she brings her grandmothers vase. long story short, it gets broke and lessons get learned all the way around. thanks for your help!!
