I am looking for the title of a song my mother used to listen to when I was young.

This is a long shot, but when I was young in the 70's and 80's my mother used to listen to the same record album every Sunday morning. I am looking for the title of one of the songs as a gift I am going to give her. I only remember part of the lyrics and googling the portion I know has yielded no results. Here is the small portion of lyrics I remember:

"If I could do a miracle, before your very eyes,

Would you believe in me, would you believe in me.

Blessed are those who have not seen, and yet believe

and yet believe."

Any help with the title would be appreciated.
