If I Awake to Flames After I Die

[Pyxx]

If I awake to flames after I die
to make eternal payment for my sin,
I will not raise my voice to question why
remembering the man that I had been.
But cast into oblivion, if He,
the Perfect Judge, should look my way with grace
and offer lovingly to pardon me
if only I would run again life’s race
more faithfully, without conceited pride,
the greed-filled lies, the lust, this time to live:
my passions and my past to set aside…
I know one thing alone I'd never give.
Those moments spent with you I would not sell
to save my soul eternity in hell.

I enjoyed reading your work, the beginning...

If I awake to flames after I die
to make eternal payment for my sin,
I will not raise my voice to question why
remembering the man that I had been.

Flows rather well and works to introduce the next lines in the piece, the use of 'sin' and 'been' is a good creative decision for your rhyme and contributes toward the continuity of the work. My suggestion is to take more chances with your choice of rhyme otherwise the work risks becoming monotonous. Your Sonnet feel 'natural' though, as if you do not struggle too much with the creation of your poetry.
