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.

A man preacheth that sermon only well unto others which preacheth itself in his own soul. And he that doth not feed on and thrive in the digestion of the food which he provides for others will scarce make it savoury unto them; yea, he knows not but the food he hath provided may be poison, unless he have really tasted of it himself. If the word do not dwell with power in us, it will not pass with power from us.

For to pretend that men may live habitually sinful lives without any attempt by the Spirit to mortify sin in them, nor with any desire for repentance, is to deny the Christian religion.

The vigour, and power, and comfort of our spiritual life depends on the mortification of the deeds of the flesh.

We ought as much to pray for a blessing upon our daily rod as upon our daily bread.

Whatever vices and corruptions men see in the lives of their ministers will not be attributed to the depravity of their old nature which still abides in them, but to the gospel.

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.
