Grace is a divine provision for those who
are so depraved they cannot change their
own nature, so averse from God they will not
turn to Him, so blind they can neither see their
malady nor the remedy, so spiritually dead...
Grace is the sinner's last and only hope;
if he is not saved by grace, he will never be
saved at all. Grace levels all distinctions,
and regards the most zealous religionist
on the same plane as the most profligate,
the chaste virgin as the foul prostitute.
Therefore God is perfectly free to save the
chief of sinners and bestow His mercy on
the vilest of the vile.
