Hatred of sin as sin, not only as galling or disquieting, a sense of the love of Christ in the cross, lie at the bottom of all true spiritual mortification.

Though we are commanded to 'wash ourselves', to 'cleanse ourselves from sins', to 'purge ourselves from all our iniquities', yet to imagine that we can do these things by our own efforts is to trample on the cross and grace of Jesus Christ. Whatever God works in us by his grace, he commands us to do as our duty. God works all in us and by us.

The mortification of indwelling sin remaining in our mortal bodies, that it may not have life and power to bring forth the works or deeds of the flesh is the constant duty of believers.

He who prays as he ought will endeavor to live as he prays.

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.'

In the divine Scriptures, there are shallows and there are deeps; shallows where the lamb may wade, and deeps where the elephant may swim.

It is not the glorious battlements, the painted windows, the crouching gargoyles that support a building, but the stones that lie unseen in or upon the earth. It is often those who are despised and trampled on that bear up the weight of a whole nation.
