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.
John OwenSin aims always at the utmost; every time it rises up to tempt or entice, if it has its own way it will go out to the utmost sin in that kind. Every unclean thought or glance would be adultery if it could, every thought of unbelief would be atheism if allowed to develop. Every rise of lust, if it has its way reaches the height of villainy; it is like the grave that is never satisfied. The deceitfulness of sin is seen in that it is modest in its first proposals but when it prevails it hardens menโs hearts, and brings them to ruin.
John Owen
