Most believers know they have a sin nature. They feel it every morning. The sin nature is the root of the problem every one of us live with every day. Neither you nor I are equipped to battle it — but there is victory over the sin nature, and the Cross is where it was secured.
Romans 6:1-6 is not a devotional passage. It is a legal record of a completed event.
Romans 6:6 declares that the old man — the pre-conversion self defined entirely by the sin nature — was crucified with Christ at Calvary. The Greek word translated destroyed is katargeo, meaning rendered inoperative. The sin nature was not eradicated. It was stripped of its ruling power. The Cross secured that reality. Faith anchored there gives the Holy Spirit latitude to make it operational in daily life.
The Facts of Romans 6:1-6
Paul does not begin this passage with a command. He begins with a question — one he knows the reader will instinctively ask after reading Romans 5.
What shall we say then? Shall we continue in sin, that grace may abound? God forbid. How shall we, that are dead to sin, live any longer therein? (Romans 6:1-2)
The logic Paul builds from here is not motivational. It is historical. He points the believer back to something that already happened — something that happened at the moment of salvation, whether the believer felt it or not.
Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death? Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life. (Romans 6:3-4)
Baptized into his death is not water baptism. Paul is describing spiritual union — the moment faith joined the believer to Christ so completely that what happened to Christ at Calvary happened to the believer as well. He died. The believer died. He was buried. The believer was buried. He rose. The believer rose.
These are not metaphors for moral progress. They are statements of positional fact.
The Old Man and the Body of Sin
Verse 6 is the doctrinal center of the passage.
Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin. (Romans 6:6)
The old man is the pre-conversion self — the person who lived entirely under the dominion of the sin nature. The old man is not identical to the sin nature, but he was completely defined by it. Every impulse, every habit, every pattern of life was shaped by it. That old man was crucified with Christ.
The body of sin in this verse refers to the sin nature itself — the inherited bent toward independence from God that entered through Adam. The KJV renders it destroyed — but the Greek behind that word is katargeo, and destroyed is too strong. It means rendered inoperative. Stripped of authority. Put out of commission.
The sin nature is still present. Every believer still feels it. But it no longer has the legal right to rule. Its power was broken at the Cross — not by the believer’s effort, not by spiritual maturity, but by what Christ accomplished.
Why the Believer Still Struggles
If the sin nature was rendered inoperative at the Cross, why does Monday morning feel like Romans 7?
Because katargeo describes a positional reality, not an automatic experience. The sin nature has been stripped of its ruling power — but the flesh still responds to it when the believer’s faith is not anchored correctly.
The battle Paul describes in Romans 7 is close to what normal Christian life looks like for most believers. It is the result of trying to overcome the sin nature by means of the law — by effort, resolve, and moral determination. The more the believer focuses on fighting the sin nature directly, the more ground it gains. That is not coincidence. That is the design of a battle fought with the wrong weapon.
This is not positive thinking. This is a specific theological truth about where the Holy Spirit operates. The Spirit works in proportion to where faith is anchored. When the object of faith is Christ and Him crucified, the Holy Spirit has latitude to work in the believer’s life and produce the victory that Calvary secured. When the object of faith shifts to self-effort — to religious discipline, willpower, or moral performance — the Cross is bypassed. The Holy Spirit is given no ground to work. The sin nature fills the vacuum.
That daily anchoring of faith to the Cross is what it means to reckon yourself dead to sin — and it is more specific than it sounds.
Galatians 2:20 — The Lived Reality
Galatians 2:20 is not a description of a spiritual elite. It is a description of what the facts of Romans 6 look like in daily experience when faith is rightly placed.
I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me. (Galatians 2:20)
I am crucified with Christ — that is the Romans 6:6 reality, stated personally. Not a theological position Paul holds at a distance. A fact he has applied to his own life.
The life which I now live in the flesh I live by the faith of the Son of God — this is the mechanism. Present tense. Ongoing. The victory is not a crisis experience Paul arrived at once and left behind. It is a daily living by faith in what Christ accomplished.
Galatians 2:20 is not the destination at the end of a long spiritual climb. It is where every believer lives when the Cross is the object of faith and the Holy Spirit has latitude to work. It is accessible now. Today. Not after enough years or enough sanctification. The only condition is faith placed where Paul placed it — in the Son of God who loved him and gave himself.
