It being our duty to mortify... we must be at work. He that is appointed to kill an enemy, if he leave striking before the other ceases living, does but half his work.

The vigour, and power, and comfort of our spiritual life depends on the mortification of the deeds of the flesh...The choicest believers, who are assuredly freed from the condemning power of sin, ought yet to make it their business all their days to mortify the indwelling power of sin...Do you mortify; do you make it your daily work; be always at it whilst you live; cease not a day from this work; be killing sin or it will be killing you.

It is truth alone that capacitates any soul to glorify God.

It is evident that you contend against sin merely because of how it troubles you.

The foundation of true holiness and true Christian worship is the doctrine of the gospel, what we are to believe. So when Christian doctrine is neglected, forsaken, or corrupted, true holiness and worship will also be neglected, forsaken, and corrupted.

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.

Temptation is like a knife, that may either cut the meat or the throat of a man; it may be his food or his poison, his exercise or his destruction
