Could it be this one by any chance? I remembered enough of it from Sunday School to do a web search. Although after 14 years, I don't really expect an answer from the OP.

When He cometh, when He cometh,
To make up His jewels,
All His jewels, precious jewels,
His loved and His own.

Refrain:
Like the stars of the morning,
His bright crown adorning,
They shall shine in their beauty,
Bright gems for His crown.

He will gather, He will gather
The gems for His kingdom,
All the pure ones, all the bright ones,
His loved and His own.

Little children, little children,
Who love their Redeemer,
Are the jewels, precious jewels,
His loved and His own.
