Topic: Where an I find words to a song. Do it again lord

Hello, I have tried and tried to find a song the only words that I know are do it again Lord do it again, let you miracles of mercy never end, do it again lord do it again heal not only the sick but heal those full of sin. It's a great song the last time I heard it was in the late 60's early 70's. I would greatly appreciate any help you can give.  Thank you.
