From Mark Seifrid of Southern Baptist Theological Seminary:

perspectives-on-our-inner-struggle“Paul does not speak of the Christian struggle with sin in Romans 7. He describes a battle already lost, long ago in Adam. Nevertheless, in sheer wonder, the long-lost battle has been decided in our favor by God in Christ. The Christian is thus called to walk the very narrow path marked by the intersection of the new creation with the present fallen world. On the one side we are subject to the danger of the despair that loses sight of God’s work in Christ. On the other hand, we are subject to the danger of a pride that falsely supposes that the power of salvation is now ours, if only we realize its potential. Such a pride in its own way also loses sight of God’s work in Christ. It brings a ‘therapeutic Christianity’ that turns outward achievements, whether individual, corporate, or social, into a measure of spiritual progress and a mark of the presence of the kingdom. It does not see that what has been accomplished in Christ is located abidingly in Christ, not in ourselves. Our salvation, and therefore all true progress, both individual and corporate, does not rest in our hands…

As Paul tells the Philippians, progress is a progress in faith (Phil 1:21). It is not a turning inward but a being-turned-outward. It is hearing the address of the gospel afresh within the changing circumstances of life. To use Paul’s language, it is again and again ‘reckoning yourselves to be dead to sin, but alive to God in Christ Jesus’ (Rom 6:11)… Not only the first step but every step of Christian progress begins with Paul’s sober and realistic confession in Rom 7:25b [...with my flesh I serve the law of sin]. It begins with the acknowledgment that as long as we remain in this body and life the unhappy truth that we ‘serve the law of sin’ remains.”
