“Are You Lost in Sin” is a gospel song that entered the bluegrass repertoire through Jim and Jesse. The McReynolds brothers cut it among the run of recordings they made for Capitol Records in the early 1950s — sessions that introduced their close brother harmony and Jesse’s distinctive mandolin to a national audience — and the song became part of the sacred material associated with them.
Like much bluegrass gospel, it puts its message as a direct question to the listener: a plain, urgent appeal about the soul’s standing and the need to be found rather than lost. That directness, set in a brisk quartet arrangement, made it a natural inclusion in the gospel sets bluegrass bands traditionally fold into their shows.
J.D. Crowe and the Kentucky Mountain Boys recorded “Are You Lost in Sin” on their 1971 gospel album The Model Church. The song has continued to draw younger traditional bands, a sign of how durable the early Jim and Jesse catalog has proved.
