All other ways of mortification are vain, all helps leave us helpless; it must be done by the Spirit.

Be killing sin or it will be killing you.

He works in us and with us, not against us or without us; so that his assistance is an encouragement to the facilitating of the work, and no occasion of neglect as to the work itself.

He that stands still and suffers his enemies to double blows upon him without resistance, will undoubtedly be conquered in the issue.

Mortification from a self-strength, carried on by ways of self-invention, unto the end of a self-righteousness, is the soul and substance of all false religion in the world.

We need to attend diligently to the state of our soul, and to deal fervently and effectively with God about it.

Sin also carries on its war by entangling the affections and drawing them into an alliance against the mind. Grace may be enthroned in the mind, but if sin controls the affections, it has seized a fort from which it will continually assault the soul. Hence, as we shall see, mortification is chiefly directed to take place upon the affections.
