Christ by his death destroying the works of the devil, procuring the Spirit for us, hath so killed sin, as to its reign in believers, that it shall not obtain its end and dominion.
John OwenSin 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.
John OwenLet no man pretend to fear sin that does not fear temptation also! These two are too closely united to be separated. He does not truly hate the fruit who delights in the root.
John OwenWhen sin lets us alone we may let sin alone; but as sin is never less quiet than when it seems to be most quiet, and its waters are for the most part deep when they are still, so ought our contrivances against it to be vigorous at all times and in all conditions, even where there is least suspicion.
John Owen
