'Faith in Christ' in the Bible

But some days later Felix arrived with Drusilla, his wife who was a Jewess, and sent for Paul and heard him speak about faith in Christ Jesus.

nevertheless knowing that a man is not justified by the works of the Law but through faith in Christ Jesus, even we have believed in Christ Jesus, so that we may be justified by faith in Christ and not by the works of the Law; since by the works of the Law no flesh will be justified.

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

and may be found in Him, not having a righteousness of my own derived from the Law, but that which is through faith in Christ, the righteousness which comes from God on the basis of faith,

since we heard of your faith in Christ Jesus and the love which you have for all the saints;

For even though I am absent in body, nevertheless I am with you in spirit, rejoicing to see your good discipline and the stability of your faith in Christ.
