Still paying, still to owe.
Eternal woe!

Say they who counsel war; ‘we are decreed, Reserved, and destined to eternal woe; Whatever doing, what can we suffer more, What can we suffer worse?’ Is this then worst, Thus sitting, thus consulting, thus in arms?
What when we fled amain, pursued and struck
With Heaven's afflicting thunder, and besought
The Deep to shelter us? This Hell then seemed
A refuge from those wounds. Or when we lay
Chained on the burning lake? That sure was worse.

Son of Heav'n and Earth,
Attend: That thou art happy, owe to God,
That thou continu'st such, owe to thyself,
That is, to thy obedience; therein stand.
This was that caution giv'n thee; be advis'd.
God made thee perfect, not immutable;
And good he made thee, but to persevere
He left it in thy power, ordain'd thy will
By nature free, not overrul'd by Fate
Inextricable, or strict necessity;
Our voluntary service he requires,
Not our necessitated, such with him
Finds no acceptance, nor can find, for how
Can hearts, not free, be tri'd whether they serve
Willing or no, who will but what they must
By Destiny, and can no other choose?
Myself and all th'Angelic Host that stand
In sight of God enthron'd, our happy state
Hold, as you yours, while our obedience holds;
On other surety none; freely we serve,
Because wee freely love, as in our will
To love or not; in this we stand or fall:
And some are fall'n, to disobedience fall'n,
And so from Heav'n to deepest Hell; O fall
From what high state of bliss into what woe!
--Archangel Raphael to Adam, Paradise Lost Book V

Him the Almighty Power
Hurled headlong naming from the ethereal sky,
With hideous ruin and combustion, down
To bottomless perdition ; there to dwell
In adamantine chains and penal fire,
Who durst defy the Omnipotent to arms.

What in me is dark
Illumine, what is low raise and support,
That to the height of this great argument
I may assert eternal Providence,
And justify the ways of God to men. 1
Paradise Lost. Book i. Line 22.

This horror will grow mild, this darkness light.
