John Owen, page 94 of Kapic/Taylor translation of "Overcoming" :

Such a person (who only can see the "fear of hell" motivation to fight sin)
has cast off, as to the particular spoken of, the conduct of
renewing grace and is kept from ruin only by restraining grace; and so far is
he fallen from grace and returned under the power of the law. And can it be
thought that this is not a great provocation to Christ, that men should cast
off his easy, gentle yoke and rule, and cast themselves under the iron yoke of
the law, merely out of indulgence unto their lusts?
Try yourself by this also: When you are by sin driven to make a stand,
so that you must either serve it and rush at the command of it into folly, like
the horse into the battle, or make head against it to suppress it, what do you
say to your soul? What do you expostulate44 with yourself? Is this all—“Hell
will be the end of this course; vengeance will meet with me and find me out”?
It is time for you to look about you; evil lies at the door [Gen. 4:7]. Paul’s
main argument to evince that sin shall not have dominion over believers is
that they “are not under the law, but under grace” (Rom. 6:14). If your contendings
against sin be all on legal accounts, from legal principles and
motives, what assurance can you attain unto that sin shall not have dominion
over you, which will be your ruin?
Yea, know that this reserve will not long hold out. If your lust has driven
you from stronger gospel forts, it will speedily prevail against this also. Do
not suppose that such considerations will deliver you, when you have voluntarily
given up to your enemy those helps and means of preservation
which have a thousand times their strength. Rest assuredly in this, that
unless you recover yourself with speed from this condition, the thing that
you fear will come upon you. What gospel principles do not, legal motives
cannot do.
