'In Christ' in the Bible

and I was unknown by face to the assemblies of Judaea, which were in Christ;

and that was because of the false brethren secretly introduced, who, indeed, crept in to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage;

yet knowing that a man is not justified by works of law, but through faith in Jesus Christ, even we believed on Christ Jesus, that we might be justified by faith in Christ, and not by works of law; because by works of law no flesh shall be justified.

But, if while seeking to be justified in Christ, we ourselves also were found sinners, is, then, Christ a minister of sin? It could not be!

for ye are all sons of God through faith in Christ Jesus;

There exists neither Jew nor Greek, there exists neither bond nor free, there exists neither male nor female; for ye are all one in Christ Jesus.

For in Christ Jesus neither circumcision avails anything, nor uncircumcision, but faith working through love.
