That white devil!
While the disciples were healing diseases and
casting out demons, the proud white devil was a-stirring in
their own souls; as is evident by that gentle rebuke which
our Savior gives them in Luke 10:20, "Don't rejoice that the
spirits submit to you." There is no pious duty which a
Christian performs, but one white devil or another--one lust
or another--will be still dogging and following of him to
that duty. There is no public duty, there is no family duty,
there is no private duty which a Christian performs--but
either that white devil pride,
or that white devil hypocrisy,
or that white devil vainglory;
or else some one or another white
devil will follow the soul, near at heel to it.
(Thomas Brooks, The Privy Key of Heaven,
1665
