The song linked above was sung on Wednesday at the T4G conference. I'm glad to be able to find the lyrics; it was immensely moving at the time to me, but something (on which I may write more, later) distracted me from full enjoyment.
If this is a copyright violation, someone please tell me; but here are the first two verses:
HOW DEEP THE FATHER’S LOVE FOR US,You can get an idea of the tune here. Thank God for those who can put the precious truths of the Gospel to music. Al Mohler made the point in his talk that some who are trying to destroy the truth of penal substitutionary atonement lament that, even if it is banished from the pulpits, when Christians assemble, they'll still sing about it.
How vast beyond all measure,
That He should give His only Son
To make a wretch His treasure.
How great the pain of searing loss –
The Father turns His face away,
As wounds which mar the Chosen One
Bring many sons to glory.
Behold the man upon a cross,
My sin upon His shoulders;
Ashamed, I hear my mocking voice
Call out among the scoffers.
It was my sin that held Him there
Until it was accomplished;
His dying breath has brought me life –
I know that it is finished.
