Thank you, thank you, thank you, I have spent all moring trying to find this song, I am a Gospel singer and used to sing this song in my ministry, just misplaced the words.
May God Bless You,

Here are the lyrics...
More: The Parson Family

If I could find the right words to say, to tell you just what Christ means to me.
I'd say He's more than I could show, and more than you'll ever know.
(Chorus)
Christ means more to me than you'll ever know.
Christ means more to me than I could possibly show.
More, more, so much more, more than you'll ever know.

If you could have seen me just yesterday, you'd know why He's life, and breath to me.
You'd know why He's more than I could show, and more than you'll ever know.
(chorus)

I just noticed how old this request is...D'oh!

I heard that song by The Parsons Family back in 1980 at my church.
Of course I've long since worn out the record, but I hope this information will help you in your search.

Some of the lyrics:

More, more, so much more,
Christ means more to me than I could possibly show

more than you'll ever know.
