The duties God requires of us are not in proportion to the strength we possess in ourselves. Rather, they are proportional to the resources available to us in Christ. We do not have the ability in ourselves to accomplish the least of God's tasks. This is the law of grace. When we recognize it is impossible for us to perform a duty in our own strength, we will discover the secret of its accomplishment.
John OwenA true saving knowledge of sin is to be had only in the Lord Christ: in him may we see the desert of our iniquities.
John OwenThe vigour, and power, and comfort of our spiritual life depends on the mortification of the deeds of the flesh.
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
