Paul explained the 'convert' even though Saved still had a 'law of sin' in their flesh, Romans 7 explains that, Paul did things at times he didnt want to do, but wondered why he did those things, then taught that the law of sin brought his members into 'captivity', he even said it wasnt HIM that was doing it , but the 'law of sin' in his flesh, he goes on teach that the law of sin, will be done away with with the Resurrection Body, like Christ's. thats why he taught, Oh wretched man that I am, who shall deliver me from this body of this death? Paul taught to walk in the Spirit, as He leads... Paul said he 'served' Law of God, the Law of Christ , which is Spiritual with his mind, but at times had the law of sin in his flesh getting in the way.... the Law of Christ, the Law of 'faith' he said he established, not the carnal commandments, those were Fulfilled in Christ's work at the tree.. those Genuinely led of the Spirit of God, NO CONDEMNATINON!! none what so ever, not 1/100000000000000000000000000000000000000000000000000000000 of a milligram to put it lightly.!
If one gets caught up in the Flesh, and continues, the Spirit of God, will lead you out of that! He will help you and lead you out of it.. because the 2 lusteth against each other..
Now the body is Dead because of sin, but the spirit alive because of Righteousness, ! ----> this righteousness by mans fulfilling the Law ? no.. but because of Faith in Christ! the Law of Faith!.... led of the Spirit, IN CHRIST!
