The seed of every sin is in every heart.

The Scripture abounds in commands and cautions for our utmost diligence in our search and inquiry as to whether we are made partakers of Christ or not, or whether His Spirit dwells in us or not-which argue both the difficulty of attaining an assured confidence herein, as also the danger of our being mistaken, and yet the certainty of a good issue upon the diligent and regular use of means to that purpose.

We speak much of God, can talk of him, his ways, his works, his counsels, all the day long; the truth is, we know very little of him.

Spiritual wisdom consists in finding out the subtleties, policies, and depths of any indwelling sin... to trace this serpent in all its turnings and windings; be able to say, at its most secret actings, 'This is your old way and course; I know what you aim at.'

Not to be daily mortifying sin, is to sin against the goodness, kindness, wisdom, grace, and love of God, who hath furnished us with a principle of doing it.
