Yes inwardly. Not through observance to a Law that was given to Moses. We are Jews by faith.
Here's the next 2 verses to that Scripture.
15We ourselves are Jews by birth and not Gentile sinners;
16yet we know that a person is
not justified by works of the law but through
faith in Jesus Christ, so we also have believed in Christ Jesus, in order to be
justified by faith in Christ and
not by works of the law, because by works of the law
no one will be justified.
Like I said, Peter and Paul didn't try to be justified by works of the Law. They sought to be justified by faith. This was Paul's biggest contention against showing preference to Jews. It caused Gentiles to want to be like them. But Peter & Paul
actual Jews by birth didn't even live like Jews, themselves. Because they understood no one is justified living by the Law. Christ is now here. And the Law has served it's purpose. To shut up all in sin, so that He might have mercy on them in Christ.
You only think this way because you have been convinced that the "Law of Works" and the "Law of Faith" are the same. But they are not as Paul said.
Rom. 3:
26 To declare,
I say, at this time his righteousness: that he might be just,
and the justifier of him which believeth in Jesus.
27 Where
is boasting then?
It is excluded.
By what law?
of works?
Nay: but by the law of faith.
The Messiah Himself said the Pharisees, those who Paul was arguing with, were following parts of the instructions given to them by God, but had omitted the most important part of God's instructions.
Matt. 23:
23 Woe unto you, scribes and Pharisees, hypocrites!
for ye pay tithe of mint and anise and cummin,
and have omitted the weightier matters of the law,
judgment, mercy, and faith:
these ought ye to have done,
and not to leave the other undone.
They had their version of the Levitical Priesthood "Works of the Law" for atonement of sins down, but rejected the "LAW of FAITH" which was also given to them by Moses.
Num. 18:
26 Thus speak
unto the Levites, and say unto them, When ye take of the children of Israel
the tithes which I have given you from them for your inheritance, then ye shall offer up an heave offering of it for the LORD,
even a tenth
part of the tithe.
But they rejected these parts of God's instruction as the Messiah said.
33 And if a stranger sojourn with thee in your land,
ye shall not vex him.
34 But the stranger that dwelleth with you shall be unto you as one born among you,
and thou shalt love him as thyself; for ye were strangers in the land of Egypt: I
am the LORD your God.
35 Ye shall do no unrighteousness in judgment, in meteyard, in weight, or in measure.
36 Just balances, just weights, a just ephah, and a just hin, shall ye have
: Iam the LORD your God, (Word which became Flesh)
which brought you out of the land of Egypt.
These are part of the Law of Mercy, Judgment and Faith that they rejected.
This was in fact the biggest contention between Paul and the Jews. The end of an obsolete Priesthood, replaced by a New Covenant that the Messiah, as the Word, promised in Jer. 31.
33 But this
shall be the covenant that I will make with the house of Israel; After those days, saith the LORD,
I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.
No more Levite Priests to administer God's Instructions.
34 And they shall teach no more every man his neighbour, and every man his brother, saying, Know the LORD: for they shall all know me, from the least of them unto the greatest of them, saith the LORD:
for I will forgive their iniquity, and I will remember their sin no more.
No more Levite Priests to perform "Works of the Law" for the cleansing of sins.
Heb. 7:
11 If therefore perfection were by the Levitical priesthood, (
for under it the people received the law,) what further need
was there that another priest should rise after the order of Melchisedec, and not be called after the order of Aaron?
12 For the priesthood being changed, there is made
of necessity a
change also of the law.
13 For he of whom these things are spoken pertaineth to
another tribe, of which no man gave attendance at the altar.
14 For
it is evident that our
Lord sprang out of Juda; of which tribe
Moses spake nothing concerning priesthood.
The Messiah is the High Priest which replaced the Levitical Priesthood. But He was from Judah, not a Levite. So the Law was "Changed" to allow Him and anyone who He brings into His Fold to enter the Holy of Holies.
No mention of the destruction of God's Commandments, no mention of the rejection of His Sabbath. All that talk is from religious man. The Bible does not support such doctrines, at least if one takes ALL God's Word's into consideration.
