'In Christ' in the Bible

I was still unknown by sight to the churches of Judea which were in Christ;

But it was because of the false brethren secretly brought in, who had slipped in to spy out our freedom which we have in Christ Jesus, in order to bring us into bondage.

yet who know that a man is not justified by works of the law but through faith in Jesus Christ, even we have believed in Christ Jesus, so that we may be justified by faith in Christ, and not by works of the law, because by works of the law will no flesh be justified.

But if, while seeking to be justified in Christ, we ourselves have also been found sinners, is Christ then an agent of sin? Certainly not!

in order that in Christ Jesus the blessing of Abraham might come to the Gentiles, so that we might receive the promise of the Spirit through faith.

For you are all sons of God, through faith in Christ Jesus.

There is neither Jew nor Greek, there is neither slave nor free, there is neither male nor female; for you are all one in Christ Jesus.

For in Christ Jesus neither circumcision nor uncircumcision is of any avail, but faith working through love.
