The musical, which captures the moment the Bible's 100-year-old Abraham tells his 90-year-old wife Sarah she's going to have a baby, features work by Harnick and his collaborators, composer Donald Oliver (The Case of the Dead Flamingo Dancer) and Marc Acito (Allegiance, A Room with a View).
For The Love Of God is conceived as part of the "revuesical" In the Name of Love, with music by Oliver and lyrics by a group of lyricists that include David Zippel, Peter Mills, David Spencer and Amanda Yesnowitz.
"I'll confess that much of what I wrote is based on my marriage, which will achieve 'golden' status next year," Harnick said in a statement.
The Festival is the largest "short-musical" festival in the country, featuring five series of 15-minute world-premiere musicals by emerging and renowned artists.
The West Village Musical Theater Festival performs at the Players Theater June 19-29. Tickets are available at Brown Paper Tickets.
