'As tow' or tinder.
A subsidiary reference may be intended to the sinful man as easily
catching fire at temptation. But the main thought is that sin makes a
man ready for destruction, 'whose end is to be burned.'
The materials for retribution are laid up in a man's nature by
wrong-doing. The conspirators store the dynamite in a dark cellar.
Conscience and memory are charged with explosives.
If tendencies, habits, and desires become tyrannous by long indulgence
and cannot be indulged, what a fierce fire would rage then!
We have only to suppose a man made to know what is the real moral
character of his actions, and to be unable to give them up, to have
hell.
All this is confirmed by occasional glimpses which men get of
themselves. Our own characters are the true Medusa-head which turns a
man into stone when he sees it.
What, then, are we really doing by our sins? Piling together fuel for
burning.
