The Ongoing Struggle with Sinful Nature in Christian Life

The ongoing struggle with sinful nature is a reality that every Christian faces, as Paul writes in Romans 8:28 that "we know that for those who love God all things work together for good," yet this does not exempt believers from the ongoing battle with sin. This struggle arises from the remaining corruption of sin in the believer's heart, which, although pardoned and being sanctified, still experiences the pull of sinful desires and inclinations. The Reformed tradition, following Scripture, acknowledges that believers are simultaneously justified and yet still sinners, a doctrine often summarized as "simul justus et peccator" - at the same time justified and a sinner.

This tension between the believer's new nature in Christ and the residual effects of sin is a central theme in Reformed theology, emphasizing the necessity of ongoing repentance and faith in the Christian life. It underscores the believer's dependence on God's grace, not only for initial salvation but also for daily sanctification and perseverance. The struggle with sinful nature serves as a reminder of the believer's need for constant communion with God, seeking His strength and grace to overcome sin and live a life that honors Him.

In addressing this struggle, it's crucial to recognize that Scripture does not promise the eradication of sin in this life but rather provides the means to mortify it through the power of the Holy Spirit. This truth addresses the misconception that Christians can achieve sinless perfection in this life, highlighting instead the importance of a gospel-centered life where believers find their identity and hope in Christ's righteousness, not their own.
