...That is a chicken and egg question ....Keeping the law does not save!
Does this mean we can disobey God and be saved?
Paul's main argument against the Law was two fold. The first (and explained in the first half of Galatians) was that the works of the Law could not justify a man.
Justification is a legal language that is borrowed from the courts. In Scriptures, the term justify does not mean to make one righteous. It means, as far as the Law is concerned, they are declared righteous. God declares, as far as I am concerned, in regards to God's Law, I am throughly acquitted.
The issue of the Law as a justifier comes up because men came into the Galatian church and told them that salvation is not by faith... justification is not by faith... it is by works of the Law. Gentiles could not be saved (justified) unless they were circumcised and kept the Mosaic Law. The first half of the letter to the Galatians shows them that justification was always been by faith.
Justification does not suggest the infusion of moral qualities or the creation of right conduct. It implies that justification of the ungodly, who believes on the basis of the justifying action of God in the death and resurrection of Jesus. The temptation is to smuggle character into justification and for some reason make that the reason God justifies me.
So clearly did Paul teach it that he was accused of "teaching the men should keeping sinning so grace can abound".
This misunderstanding of Paul's Gospel is one of the main reasons why Jewish believers (Judiazers) were so concerned with having Gentiles keep the Law. If the Law has been set aside, what would keep these pagan Gentiles from living like heathens. Without rules such as "thou shalt not kill, or thou shalt not commit adultery" how would these heathens ever learn holiness.
Paul never compromises on the issue of holiness. Character is important. But, Paul (in the 2nd part of Galatians) uses the argument of the indwelling Christ as the teacher of true holiness. Who would teach these pagans? The Holy Spirit would teach them. When Paul comes up against a local church behaving improperly, he would exhort them with such sentences as "you have not so learned Christ."
The standard of behavior was never the Law. The standard of behavior, the plumb line, was always Christ. Only Christ can teach Christ. Does Christ disobey God? No.
Jesus says by their fruit you shall know them. If a man says he is a saint, but acts like a heathen then I would have my doubts. If a man says that he has the truth but hates his brother, then I would probably not listen to his truth because it is not borne out in his life. It is in his life that Christ is known. (And I am talking about a pattern of consistent behavior)
So, to answer your question... can a man disobey God and still be saved is relative. Can a man live his whole life disobeying God and still be saved? No. Example: If someone came up to me and said that he was saved but he was never faithful to his wife and has had numerous affairs in the past and planned to have some in the future... and didn't really care that God said "thou shalt not commit adultery". Then no. Can a man sin (which is disobeying God) repent and be restored. Yes.
Colleen it means just what I said it means..keeping the law does not save anyone..that is salvation by self effort and works..The Blood of Jesus saves us..Rom 5:8 But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us.
He paid the price for us..and in Hebrews we read we now have a high priest read Hebrews 9
Hbr 9:28 So Christ was once offered to bear the sins of many; and unto them that look for him shall he appear the second time without sin unto salvation
The purpose of the law was to demonstrate to us that we are sinners...we can never keep the law perfectly..let alone earn our way to heaven with it..
