'Whom' in the Bible

in whom we have redemption [because of His sacrifice, resulting in] the forgiveness of our sins [and the cancellation of sins’ penalty].

God [in His eternal plan] chose to make known to them how great for the Gentiles are the riches of the glory of this mystery, which is Christ in and among you, the hope and guarantee of [realizing the] glory.

and not holding fast to the head [of the body, Jesus Christ], from whom the entire body, supplied and knit together by its joints and ligaments, grows with the growth [that can come only] from God.

and in these [sinful things] you also once walked, when you were habitually living in them [without the knowledge of Christ].

knowing [with all certainty] that it is from the Lord [not from men] that you will receive the inheritance which is your [greatest] reward. It is the Lord Christ whom you [actually] serve.
