Isaiah 42:6, 7: Adam descended from above

Adam descended from above,
Federal Head of all mankind.
The covenant of redeeming love
In Thee let every sinner find:
Its Surety Thou alone hast paid
The debt we to Thy Father owed,
For the whole world atonement made,
And seal'd our pardon with Thy blood.

Thee the paternal Grace Divine
An universal Blessing gave,
A Light, in every heart to shine,
A Saviour, every soul to save:
Light of the Gentile world, appear,
Command the blind Thy rays to see.
Our darkness chase, our sorrows cheer.
And set Thy plaintive prisoners free.

Me, me who still in darkness sit.
Shut up in sin and unbelief,
Bring forth out of this hellish pit,
This dungeon of despairing grief;
Open mine eyes the Lamb to know
Who bears the general sin away.
And to my ransom'd spirit show
The glories of eternal day.
