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.
John OwenIf a man teach uprightly and walk crookedly, more will fall down in the night of his life than he built in the day of his doctrine.
John OwenMortification is the soul's vigorous opposition to self, wherein sincerity is most evident.
John OwenThe 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.
John Owen
