Found in a forum at CowboyLyrics.com. It doesn't give a title:

PLEASE SEARCH THE BOOK AGAIN
written by Jerry Goff

1. I thought that I had died and gone to heaven.
I was standing just outside the gate.
The man from within said, "Have you been born again?
Is your name written in the Book of Life?"

CHORUS: Please search the book again. I thought my name was there.
I went to church on Sunday, though I never knelt in prayer.
Please search the book again before you make me go.

2. I told him of the deeds I had done.
I told him of the trophies I had won.
Then the man said to me, "Son, have you been set free?
Is your name written in the Book of Life?"

3. And then he turned and left me standing there.
I knew it was too late now for prayer.
So, my sinner friend, if you will enter in,
Your name must be in the Book of Life.
