'In Christ' in the Bible

I always thank God for you, [especially] for God's unearned favor that was given to you [in providing salvation and blessings] in Christ Jesus.

For since, according to God's [true] wisdom, the world did not know about Him through its wisdom, God was pleased to save those who believe [in Christ] through the "foolishness" of the message preached.

After all, who is Apollos? And who is Paul? They are [only] servants through whom you believed [in Christ], with each one doing what the Lord gave him to do.

If we have placed our hope in Christ while in this life only, we are to be pitied more than all [other] people.

I face death every day, I assure you brothers, as surely as I boast of [fellowship with] you in Christ Jesus our Lord.
