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 OwenWhen 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.
John OwenWhen the Holy Spirit sanctifies believers, he does a complete work in them. He puts into their minds, wills and hearts a gracious, supernatural principle which fills them with a holy desire to live to God. The whole life and being of holiness lies in this. This is the new creation.
John OwenYour state is not at all to be measured by the opposition that sin makes to you, but by the opposition you make to it.
