“The first and the worst cause of errors, that prevail in such a state of
things, is spiritual pride. This is the main door by which the devil comes
into the hearts of those who are zealous for the advancement of religion. It
is the chief inlet of smoke from the bottomless pit, to darken the mind and
mislead the judgment. This is the main handle by which the devil has hold
of religious persons, and the chief source of all the mischief that he
introduces, to clog and hinder a work of God…Till this disease is cured,
medicines are in vain applied to heal other diseases.”
-Jonathan Edwards
