I've got the joy

I've got the joy, joy, joy, joy down in my heart, (where?) down in my heart, (where?), down in my heart, I've got the joy, joy, joy, joy down in my heart, (where?) down in my heart to stay. I've got the peace that passes understanding down in my heart I've got the love of Jesus, love of Jesus, down in my heart I've got the wonderful love of my blessed redeemer way down in the depths of my heart
