Yes. A righteousness apart from the law. Because the law is not of faith. Our righteousness is PURELY by faith in Christ.
Yes, a righteousness apart from the law, that is nevertheless attested to by the law and the prophets that it is righteousness indeed.
Because it is not obtained through attempting to obey a set of do's and don'ts; but by faith in Jesus through whom we receive the Holy Spirit (Galatians 3:14); and then, as we bear His fruit, we become law-abiding citizens of the kingdom of heaven (Galatians 5:22-23, Romans 8:4).
When it says that the law is not of faith, that is concerning justification and not sanctification according to the context.
Because, again, we receive the Spirit by faith; and when we walk according to the Spirit, the righteousness of the law is fulfilled in us.
And therefore, we become obedient to the spirit of the law through faith.
But as concerning justification, the law is not of faith. Which means that if I am justified by faith, I am not justified through law-keeping.
I hold that this is absolute truth; that we are not justified through the keeping of the law.
I believe that Galatians 3:10 is also in reference to justification. Those who seek to be justified through the keeping of the law are required to keep the whole law perfectly from conception into eternity. but for those who know that they are justified solely through faith in the blood of Jesus Christ, if they look into the perfect law of liberty and continue in it, they are not cursed but blessed (James 1:25). The law of liberty may also be spoken of in Romans 8:4a s related to Romans 7:6; that the righteousness of the law is fulfilled in those who walk not after the flesh but after the Spirit...not the letter, but the spirit of what is written.
