It's all right there in scripture. Unfortunately, many see Romans 7 as the life of a Spirit-filled Christian. It's not. Paul is finishing his teaching on the law. Even though the law is holy, it was the sin in us that caused the battle of mind over flesh. And because of the sin in us, the flesh was strong, and could never please God. But now through Christ, He has given us His Own Spirit and killed our fleshly desires to sin. We are dead to sin.
Under the Law
Romans 7:7 What shall we say then? Is the law sin? Certainly not! On the contrary, I would not have known sin except through the law. For I would not have known covetousness unless the law had said, “You shall not covet.” 8 But sin, taking opportunity by the commandment, produced in me all manner of evil desire. For apart from the law sin was dead. 9 I was alive once without the law, but when the commandment came, sin revived and I died.
13 Has then what is good become death to me? Certainly not! But sin, that it might appear sin, was producing death in me through what is good, so that sin through the commandment might become exceedingly sinful.
20 Now if I do what I will not to do, it is no longer I who do it, but sin that dwells in me.
22 For I delight in the law of God according to the inward man. 23 But I see another law in my members, warring against the law of my mind, and bringing me into CAPTIVITY TO THE LAW OF SIN which is in my members. 24 O wretched man that I am! WHO will deliver me from this body of death? 25 I thank God—through JESUS CHRIST OUR LORD!
Don't you see this is a recollection of all BEFORE CHRIST about those under the law? The law, holy as it is, didn't make them holy, because they still had SIN in their heart, so there was a constant battle. And when the flesh overcame their mind and they sinned - they were CONDEMNED.
Under Christ
Romans 8:1There is therefore now NO CONDEMNATION to those who are in Christ Jesus, who do not walk according to the flesh, but according to the Spirit. 2 For the law of the Spirit of life in Christ Jesus has made me free from the law of sin and death. 3 For what the law could not do in that it was weak through the flesh, God did by sending His own Son in the likeness of sinful flesh, on account of sin: He condemned sin in the flesh, 4 that the righteous requirement of the law might be fulfilled in us who do not walk according to the flesh but according to the Spirit.
8 So then, those who are in the flesh cannot please God. 9 But you are NOT IN THE FLESH but in the Spirit, if indeed the Spirit of God dwells in you. Now if anyone does not have the Spirit of Christ, he is not His.
Romans 6: 1What shall we say then? Shall we continue in sin that grace may abound? 2 Certainly not! How shall we who DIED TO SIN live any longer in it? 3 Or do you not know that as many of us as were baptized into Christ Jesus were baptized into His death? 4 Therefore we were buried with Him through baptism into death, that just as Christ was raised from the dead by the glory of the Father, even so we also should walk in newness of life.
Martin Luther said to not only sin, but make your sins strong! That is the very opposite of Romans 6:1-2. Can't you see how devilish that teaching is???? Satan knows if he can get those claiming Christ to stay in sin, they are condemned. Even the demons believe and tremble. So who are you going to believe? Martin Luther or Paul?
I hope you know how much I care about you to write this long post to you. I haven't even had my tea yet!
Please study those scriptures. Let them speak to you. I don't want to hear from you until you pray and ask God to show you what HE MEANS, not what any man-Luther/woman-me says it means.
And I also don't want to hear from you unless you use scripture. And above all, don't use Romans 7. That would only prove you haven't studied. They were under the law. Christians, because we walk in the Spirit, are NOT under the law. If we actually have the Spirit that is. And those who claim Christ, but have no power not to sin, do not have the Spirit, and Paul says, don't belong to Christ. So this is important to you. Don't waste it.
