Even as [in His love] He chose us [actually picked us out for Himself as His own] in Christ before the foundation of the world, that we should be holy (consecrated and set apart for Him) and blameless in His sight, even above reproach, before Him in love. For He foreordained us (destined us, planned in love for us) to be adopted (revealed) as His own children through Jesus Christ, in accordance with the purpose of His will [because it pleased Him and was His kind intent]—[So that we might be] to the praise and the commendation of His glorious grace (favor and mercy), which He so freely bestowed on us in the Beloved.
Ephesians 1:4-6

That they all may be one, [just] as You, Father, are in Me and I in You, that they also may be one in Us, so that the world may believe and be convinced that You have sent Me. I have given to them the glory and honor which You have given Me, that they may be one [even] as We are one: I in them and You in Me, in order that they may become one and perfectly united, that the world may know and [definitely] recognize that You sent Me and that You have loved them [even] as You have loved Me. Father, I desire that they also whom You have entrusted to Me [as Your gift to Me] may be with Me where I am, so that they may see My glory, which You have given Me [Your love gift to Me]; for You loved Me before the foundation of the world. O just and righteous Father, although the world has not known You and has failed to recognize You and has never acknowledged You, I have known You [continually]; and these men understand and know that You have sent Me. I have made Your Name known to them and revealed Your character and Your very Self, and I will continue to make [You] known, that the love which You have bestowed upon Me may be in them [felt in their hearts] and that I [Myself] may be in them.
John 17:21-26

Be subject to one another out of reverence for Christ (the Messiah, the Anointed One). Wives, be subject (be submissive and adapt yourselves) to your own husbands as [a service] to the Lord. For the husband is head of the wife as Christ is the Head of the church, Himself the Savior of [His] body. As the church is subject to Christ, so let wives also be subject in everything to their husbands. Husbands, love your wives, as Christ loved the church and gave Himself up for her, So that He might sanctify her, having cleansed her by the washing of water with the Word, That He might present the church to Himself in glorious splendor, without spot or wrinkle or any such things [that she might be holy and faultless]. Even so husbands should love their wives as [being in a sense] their own bodies. He who loves his own wife loves himself. For no man ever hated his own flesh, but nourishes and carefully protects and cherishes it, as Christ does the church, Because we are members (parts) of His body. For this reason a man shall leave his father and his mother and shall be joined to his wife, and the two shall become one flesh.
Ephesians 5:21-31

And said, For this reason a man shall leave his father and mother and shall be united firmly (joined inseparably) to his wife, and the two shall become one flesh? So they are no longer two, but one flesh. What therefore God has joined together, let not man put asunder (separate).
Matthew 19:5-6

And this you do with double guilt; you cover the altar of the Lord with tears [shed by your unoffending wives, divorced by you that you might take heathen wives], and with [your own] weeping and crying out because the Lord does not regard your offering any more or accept it with favor at your hand. Yet you ask, Why does He reject it? Because the Lord was witness [to the covenant made at your marriage] between you and the wife of your youth, against whom you have dealt treacherously and to whom you were faithless. Yet she is your companion and the wife of your covenant [made by your marriage vows]. And did not God make [you and your wife] one [flesh]? Did not One make you and preserve your spirit alive? And why [did God make you two] one? Because He sought a godly offspring [from your union]. Therefore take heed to yourselves, and let no one deal treacherously and be faithless to the wife of his youth.
Malachi 2:13-16
