Below are how I hear the two quartet's versions. (You may hear them a little differently in some places.) If you have a different version/verse, please post it. I'd welcome an additional verse-- an old and authentic one, or I may write one myself.
LET GOD ABIDE, I Harmonizing Four version, 1950-52
Verse 1: If you are a witness, let God abide. If you've been converted, let God abide. And if you're sure you know Him, He will walk by your side You'll get an answer to every problem, let God abide.
Verse 2: When your loved ones deceive you, you just let God abide. When friends don't believe you, oh let Him abide, now. When storm clouds gather, or trouble betide, You'll find God standing right by your side, hey, let Him abide.
REFRAIN (twice): Within your soul (within your soul) Within your soul (within your soul) Within your soul (within your soul) Deep down within (deep down within) He'll hear your call; He'll never let you fall, You'll get an answer to every problem, let God abide.
