this is an old song but i love it...i do not know the name of it, and i can't remember who sings it...I have a group in mind, but I am not sure. can you please help me with this?

some of the words that I remember is:
Lord i can't form a cloud or make it rain from the skies above, but there's one thing that we all can be a part of and that is showing each other love.

thank you,
