Ongoing Sin and the Work of the Holy Spirit
The presence of ongoing sin in a believer's life can indeed be a source of unease and distress. Paul writes in Romans 8:28 that "we know that for those who love God all things work together for good," which can be a comforting truth in the midst of struggle. The fact that one is troubled by their sin suggests that the Holy Spirit is indeed at work, convicting them of their sin and stirring up a desire for holiness. This conviction is a mark of the Spirit's presence and activity in a believer's life, as it reveals a heart that is sensitive to God's standards and grieved by its own failures.
The feeling of being "eaten up" by sin can be a sign that the Holy Spirit is working to sanctify the believer, to conform them to the image of Christ. This process of sanctification is a lifelong journey, and it involves the Spirit's ongoing work of convicting, teaching, and empowering the believer to live a life that honors God. The believer's unease and distress over their sin can be seen as a manifestation of the Spirit's work, as it drives them to seek forgiveness, to repent, and to pursue a deeper walk with God.
The gospel offers hope and comfort to those who are struggling with the reality of ongoing sin. The fact that Christ has died for their sins, and that they are justified by faith alone, means that their standing before God is secure, despite their ongoing struggles with sin. This truth can bring peace and assurance to the believer, even as they continue to wrestle with the presence of sin in their life.
