Romans 7:20: Sin vs. New Nature Struggle?
How does Romans 7:20 illustrate the struggle between sin and our new nature?

Setting the Scene

Romans 7 drops us into Paul’s transparent testimony about life after conversion. He has been justified, yet he still senses a tug-of-war inside. In verse 20 he lays the tension bare:

“Now if I do what I do not want, it is no longer I who do it, but it is sin that dwells in me.”


What Paul Confesses in 7:20

• He sometimes acts against his redeemed desires—“I do what I do not want.”

• A real, personal “I” longs to obey.

• Another power, “sin that dwells in me,” hijacks the steering wheel.

• Responsibility remains, yet the verse acknowledges an indwelling principle that resists the new nature.


Two Residents in One Heart

1. The “new I”

• Born again through faith in Christ (John 3:3; 2 Corinthians 5:17).

• Desires God’s law and holiness (Psalm 119:97).

2. The “old sin principle”

• Still present in the mortal body (Romans 6:12).

• Seeks to pull the believer back to former patterns (Galatians 5:17).


Why the Conflict Matters

• It proves salvation has taken root—only a renewed heart can truly hate sin.

• It exposes the deceitfulness of residual sin, urging watchfulness (1 Peter 5:8).

• It drives dependence on the Spirit, not self-effort (Romans 8:13).


Cross-References that Illuminate the Battle

Galatians 5:17 – “For the flesh craves what is contrary to the Spirit… they are opposed to each other.”

1 John 1:8 – “If we say we have no sin, we deceive ourselves.”

Colossians 3:9-10 – “You have put off the old self… and have put on the new self.”

Philippians 2:13 – “For it is God who works in you to will and to act on behalf of His good purpose.”


Living Out the Victory

• Count the old self crucified with Christ (Romans 6:6-11).

• Feed the new nature through Scripture, fellowship, and obedience (1 Peter 2:2).

• Walk by the Spirit, who alone subdues the flesh (Galatians 5:16).

• Keep short accounts with God—confess quickly, receive cleansing (1 John 1:9).

• Look forward to the day when indwelling sin is gone forever (Revelation 21:27).
