I still can't find that CD. But, thanks to Joe's post, I remembered these lyrics. I'll write all the lyrics that I remember them:

I'M HAPPY JUST TO KNOW THAT I'M HIS CHILD [HE'S NAME IS JESUS]

I may not be the best of anything.
Have the best of anything.
Sometimes I feel that I'm the least of all
But I have someone who is everything
And he is my everything
I'm happy just to know that I'm his child.

chorus:
His name is Jesus
the righteous son of God.
He's the lily of the valley
{The} bright and morning star
His name is Jesus.
He's my everything.
{And} I am happy just to know
that I'm his child.

[I know that the chorus is repeated several times. There may be additional words, but the version of the song that I have ends with these words]:

I am happy just to know-
I am happy just to know-
I am happy just to know-
that I'm his child.

[The female singer got happy at the end and sang "Oh-o yes! Say Amen Yes!]
