Romans 8: Defines law versus New Covenant grace.

by | Posted April 2nd at 8:00am

Romans 8 addresses the relationship between the Spirit-led life, the law, and grace, emphasizing that believers are freed from condemnation and empowered to fulfill God’s will through the Holy Spirit. Below is an analysis of key themes and their connection to the law-grace dynamic and the new covenant, which gives the believer the power of the indwelling Spirit to overcome temptation:

Romans 8: The Spirit vs. the Flesh

Paul contrasts life “in the Spirit” with life “in the flesh” (Romans 8:1–8). Those led by the Spirit are no longer under the law’s condemnation (Romans 8:1) because Christ’s sacrifice fulfilled the law’s demands (Romans 8:3–4). The Spirit enables believers to live in obedience to God’s will, revealed in God’s Word—predominantly as expressed in the New Testament, not through legalistic adherence to the law but through a transformed heart. Jesus was instrumental in expanding the Old Covenant law’s viewpoints relating to even our thought life. (Matthew 5:28) ¹

Law vs. Grace in Romans 8

The Law’s Purpose: The law reveals sin but cannot provide righteousness (Romans 8:3; cf. Romans 7:5–11). It demands obedience but cannot empower it, leading to frustration (Romans 7:18–24).

Grace Through the Spirit: Believers are freed from the law’s bondage (Romans 7:6) and empowered by the Spirit to fulfill the law’s intent (Romans 8:4). Love becomes the fulfillment of the law (Romans 13:10; Galatians 5:14), as the Spirit produces fruit like love, joy, and peace (Galatians 5:22–23).

No Condemnation: Justification by faith (Romans 3:24–25) removes guilt, and the Spirit’s indwelling ensures believers are no longer slaves to sin (Romans 8:1–2).

The New Covenant in Romans 8

The new covenant, foreshadowed in Jeremiah 31:31–34 and fulfilled in Christ, replaces the old covenant’s external law with an internal transformation:

Internal Transformation: God writes His laws on believers’ hearts (Jeremiah 31:33; Hebrews 8:10), enabling obedience through the Spirit (Romans 8:5–6) and progressive sanctification (Philippians 3:12-14 ). This aligns with Romans 8:4, where the Spirit empowers believers to fulfill the law’s requirements.

Security and Assurance: The new covenant guarantees forgiveness and a permanent relationship with God (Jeremiah 31:34; Romans 8:31–39). Believers are heirs of God, assured of eternal glory despite present suffering (Romans 8:17–18). Romans 8 resolves the tension between law and grace by showing that the Spirit’s work in believers fulfills the law’s intent. This aligns with the broader theme that grace does not negate the law but transforms it into heart-driven obedience. The new covenant’s promises (Jeremiah 31:31–34) are realized in Christ, who fulfills the law and secures believers’ eternal standing.

Key Takeaways

Law vs. Grace: The law exposes sin; grace provides righteousness through Christ and empowers obedience via the Spirit.

New Covenant: Internalizes God’s law through the Spirit, ensuring forgiveness and an eternal relationship with God.

Romans 8: Affirms believers’ freedom from condemnation and their Spirit-enabled ability to live righteously. This framework underscores that the law is not abolished but fulfilled in Christ, and believers participate in this fulfillment through the Spirit’s transformative work.

Caveat Warning to Carnal vs. Spiritual Believers:

Some theologians add a saved/unsaved dichotomy, arguing that Romans 8:5–8 describes two types of believers:

Carnal Christians: Those who complacently live “in the flesh” (Romans 8:5), experiencing spiritual “death” (Romans 8:6) due to unrepentant ongoing sin or lack of Spirit-led obedience, or not adhering to sound doctrine.

Spiritual Christians: Those who walk “in the Spirit” (Romans 8:4), experiencing life and peace through active reliance on the Spirit as they live in obedience.

I believe the above caveat is very important from this perspective—to urge believers to pursue holiness through the Spirit (1 Peter 1:16). I think we need to hearken to this caution, to study the reform position on spiritual regeneration as it can save us from backsliding, and focus on the study of the biblical doctrines (scripture alone defines them) relating to the gospel of Jesus Christ.

While affirming justification (Romans 5–6), we must stress having a union with Christ (Romans 8:1) as the basis for overcoming carnality. Our union is tied to the believer’s positional identity in Christ, urging a renewed commitment to Spirit-led obedience, though, as Paul taught, was progressive sanctification (Philippians 3:12-14 ).

Theological Implications

Practical holiness defines Spirit-filled living, urging believers to pursue transformative obedience rather than resting solely in positional righteousness (of being once justified by believing in Jesus). This aligns with an emphasis on progressive sanctification and the believer’s responsibility to “walk in the Spirit.”  While acknowledging sanctification, specific interpretations often prioritize justification’s irrevocable nature (Romans 8:31–39).

A balanced view corrects complacency by urging believers to actively engage with the Spirit’s work—a theme echoed in the apostles’ writings. This exegesis of Romans 8 diverges from traditional interpretations in its focus on sanctification rather than soteriology (as in the view that Justification in Christ equates positionally to once saved, always saved), particularly in how we frame the contrast between living “in the flesh” and “in the Spirit.”

Here’s a breakdown of the theological Traditional Reform difference:

Traditional Reform Interpretation of Romans 8

Saved vs. Unsaved Contrast: Romans 8:1–8 is often viewed as a contrast between believers (in the Spirit) and unbelievers (unregenerate/unbelievers in the flesh). The Spirit’s indwelling distinguishes the regenerate, freed from condemnation and empowered to obey God’s will.

The law’s inability to save (Romans 8:3) is tied to humanity’s sinful nature, while Christ’s substitutionary atonement and His imputed righteousness fulfill the law’s demands.

Over-emphasis on Justification:

Emphasis is often placed on no condemnation (Romans 8:1) as a result of justification by faith, with the Spirit’s role in sanctification often a secondary process. Justification is the critical first step in believing in Jesus. This is true, but our further sanctification towards holiness means walking in the Spirit and obeying God’s Word — which is sanctification by the Spirit. If we over-emphasize Justification, we may miss the need to obey the Word by the indwelling Spirit of Christ as we abide in Him.

I believe that once we are justified by faith, sanctification by faith continues in lock-step if we obey scripture. If we err, we confess our sin in repentance and continue on our journey in Christ.
