“Sin does not only still abide in us, but is still acting, still laboring to bring forth the deeds of the flesh. When sin lets us alone we may let sin alone; but as sin is never less quiet than when it seems to be the most quiet, and its waters are for the most part deep when they are still, so ought our contrivances against it be vigorous at all times and in all conditions, even where there is least suspicion.”

“When we realize a constant enemy of the soul abides within us, what diligence and watchfulness we should have! How woeful is the sloth and negligence then of so many who live blind and asleep to this reality of sin. There is an exceeding efficacy nad power in the indwelling sin of believers, for it constantly inclines itself towards evil. We need to be awake, then, if our hearts would know the ways of God. Our enemy is not only upon us, as it was with Samson, but it is also in us.”

“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.”

“There must be a constant and increasing appreciation that though sin still remains it does not have the mastery. There is a total difference between surviving sin and reigning sin, the regenerate in conflict with sin and the unregenerate complacent to sin. It is one thing for sin to live in us: it is another for us to live in sin.”

“Sin also carries on its war by entangling the affections and drawing them into an alliance against the mind. Grace may be enthroned in the mind, but if sin controls the affections, it has seized a fort from which it will continually assault the soul. Hence, as we shall see, mortification is chiefly directed to take place upon the affections.”

“The difference between us and the one being disciplined by the church is not that we're not all sinners...but that we repent of our sin and he doesn't...we take God's side against our own sin”

“We (believers) still have the presence of sin, nay, the stirrings and workings of corruption. These make us to have many a sad heart and a wet eye. Yet Christ has thus far freed us from sin; it shall not have dominion. There may be the turbulence, but not the prevalence of sin...(Sin) may get into the throne of the heart and play the tyrant in this or that particular act of sin, but it shall never more be as a king there.”
