You are singling out a verse and missing what he’s talking about dear sister
“Where is boasting then? It is excluded. By what law?
of works?
Nay: but by the law of faith.
Therefore we conclude that a man is justified by faith without the deeds of the law.
Rom 3:28 Therefore we conclude that a man is justified by faith without the deeds of the law.
Rom 3:29 Is he the God of the Jews only? is he not also of the Gentiles? Yes, of the Gentiles also:
Rom 3:30 Seeing it is one God, which shall justify the circumcision by faith, and uncircumcision through faith.
Rom 3:31 Do we then make void the law through faith? God forbid: yea, we establish the law.
True our works do not save us..... Us keeping the law does not save us..... this is plainly stated.
but the question is asked
"do we then make void the law?"
No. We don't. That isn't a complicated answer it is plainly stated that the law is still valid today.
Mat 5:17 Think not that I am come to
destroy the law, or the prophets:
I am not come to destroy, but to fulfil.
Mat 5:18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
Mat 19:16 And, behold, one came and said unto him, Good Master, what good thing shall I do, that I may have eternal life?
Mat 19:17 And he said unto him, Why callest thou me good? there is none good but one, that is, God: but if thou wilt enter into life, keep the commandments.
Gal_2:16 Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might
be justified by the faith of Christ, and not by the works of the law:
for by the works of the law shall no flesh be justified.
Rom 6:1 What shall we say then? Shall we continue in sin, that grace may abound?
Rom 6:2 God forbid. How shall we, that are dead to sin, live any longer therein?
Romans 7 below explains sin.....
I had not known sin, but by the law:
Rom 6:14 For sin shall not have dominion over you:
for ye are not under the law, but under grace.
Rom 6:15
What then? shall we sin, because we are not under the law, but under grace? God forbid.
Rom 6:16 Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, or of obedience unto righteousness?
Rom 7:7 What shall we say then? Is the law sin? God forbid. Nay,
I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet.
Rom 7:8 But sin, taking occasion by the commandment, wrought in me all manner of concupiscence. For without the law sin was dead.
Rom 7:9 For I was alive without the law once: but when the commandment came, sin revived, and I died.
Rom 7:10 And the commandment, which was ordained to life, I found to be unto death.
Rom 7:11 For sin, taking occasion by the commandment, deceived me, and by it slew me.
Rom 7:12
Wherefore the law is holy, and the commandment holy, and just, and good.
Rom 7:13 Was then that which is good made death unto me? God forbid. But sin, that it might appear sin, working death in me by that which is good; that sin by the commandment might become exceeding sinful.
Rom 7:14
For we know that the law is spiritual: but I am carnal, sold under sin.
It is simple = Salvation is a gift that is not earnt and we can not gain it by keeping the law. But because Jesus has done the work for us does not give us the right to be disobedient to the law and continue in sin.
justification comes by faith and sanctification is by faith also. Sanctification is the work of God in us, learning to obey the law more and more.
