Emunah was written by Lenny Solomon and Brocho Kitowitz.   Brocho called Lenny up and said

she had written a song about Emunah and Lenny took the words and wrote the music.

The song was recorded by Lenny in 1988 and came out on the Emunah album as track 5.

Seth Stavsky composed and played the original guitar solo that appears on the recording.
