Ro 16:25 ¶ Now to him that is of power to stablish you according to my gospel, and the preaching of Jesus Christ,
according to the revelation of the mystery, which was kept secret since the world began,
26
But now is made manifest, and by the scriptures of the prophets, according to the commandment of the everlasting God, made known to all nations for the
obedience of faith:
Ga 2:11 ¶ But when Peter was come to Antioch, I withstood him to the face, because he was to be blamed.
12 For before that certain came from James, he did eat with the Gentiles: but when they were come, he withdrew and separated himself, fearing them which were of the circumcision.
13 And the other Jews dissembled likewise with him; insomuch that Barnabas also was carried away with their dissimulation.
14 But
when I saw that they walked not uprightly according to the truth of the gospel, I said unto Peter before them all, If thou, being a Jew, livest after the manner of Gentiles, and not as do the Jews, why compellest thou the Gentiles to live as do the Jews?
15 We who are Jews by nature, and not sinners of the Gentiles,
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.
17 But if, while we seek to be justified by Christ, we ourselves also are found sinners, is therefore Christ the minister of sin? God forbid.
18
For if I build again the things which I destroyed, I make myself a transgressor.
19
For I through the law am dead to the law, that I might live unto God.
20
I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me.
21 I do not frustrate the grace of God:
for if righteousness come by the law, then Christ is dead in vain.
2Co 4:4 In whom the god of this world hath blinded the minds of them which believe not,
lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them.
2Co 4:6 For God, who commanded the light to shine out of darkness, hath shined in our hearts,
to give the light of the knowledge of the glory of God in the face of Jesus Christ.
To walk "in the light" is to walk in the truth of the gospel by faith.
We see that Peter did not "walk uprightly" when he walked in the old covenant of law, for according to the law, a jew was not to eat with a Gentile.
2Co 3:13
And not as Moses, which put a vail over his face, that the children of Israel could not stedfastly look to the end of that which is abolished:
14
But their minds were blinded: for until this day remaineth the same vail untaken away in the reading of the old testament; which vail is done away in Christ.
15
But even unto this day, when Moses is read, the vail is upon their heart.
Those who are under the law are not walking in the light of the gospel.
