Sister Miriam Therese Winter (born Gloria Winter; 1938, Passaic, New Jersey) is a Roman Catholic Medical Mission Sister, theologian, writer and songwriter (e.g. "Joy Is Like the Rain" (1966), "Knock Knock" (1968), and "Wellspring of Wisdom" (1989)).
"Joy Is Like the Rain" is primarily acoustic music. All songs contain striking vocals. The recording was very popular amongst evangelicals in Britain. "Knock Knock" was similarly popular. It introduced two electric instruments: a guitar, a bass guitar and also added drums on some songs.
