'In Christ' in the Bible

For you became imitators, brothers, of the churches of God [which] are in Judea in Christ Jesus, because you also suffered the same [things] at the hands of your own people, just as [they] themselves [did] also at the hands of the Jews,

For the Lord himself will descend from heaven with a shout of command, with the voice of the archangel and with the trumpet of God, and the dead in Christ will rise first.

give thanks in everything; for this [is] the will of God for you in Christ Jesus.
