Over time, music critics have re-evaluated Cardiacs and their albums, and today "Sing to God" is considered a masterpiece, and is often regarded as the band's magnum opus. Original copies for the album command high prices in second hand retail. A reviewer for "PIEmag" said the album was considered by "many (myself included)" to be "one of the finest moments in Cardiac history. Benjamin Bland of Drowned in Sound said that "to say it's highly regarded amongst Cardiacs fans everywhere would be the understatement of the century."
