I was able to locate nine verses of this carol. Most settings do not use all of them.
This is the truth sent from above
The truth of God, the God of love
Therefore don't turn me from your door
But hearken will both rich and poor
Is that God did man create
The next thing which to you I'll tell
Woman was made with man to dwell
To place them both in Paradise,
There to remain of evil free
Except they ate of such a tree.
And so their ruin did begin,
Ruined themselves, both you and me,
And all of their posterity.
Till God and Lord did interpose
And so a promise soon did run
That He would redeem us by His Son
Our blessed Redeemer did appear
He here did live and here did preach
And many thousands he did teach
To show us how we must be saved
And if you want to know the way
Be pleased to hear what He did say
To all the nations that are made
And he that does believe in me,
From all his sins I’ll set him free.
True saving faith—that special grace,
Which to His people doth belong—
And thus I close my Christmas song.
