Romans 10:9,14:
That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved [born again and a member of the Body of Christ].
How then shall they call on him in whom they have not believed? and how shall they believe in him of whom they have not heard? and how shall they hear without a preacher?
Romans 12:4,5:
For as we have many members in one body, and all members have not the same office [function]:
So we, being many, are one body in Christ, and every one members one of another.
Romans 16:25,26:
Now to him that is of power to stablish you according to my gospel, and the preaching of Jesus Christ, according to the revelation of the mystery, which was kept secret since the world began,
But now is made manifest, and by the scriptures of the prophets, according to the commandment of the everlasting God, made known to all nations for the obedience of faith.
I Corinthians 2:7,8:
But we speak the wisdom of God in a mystery, even the hidden wisdom, which God ordained before the world unto our glory:
Which none of the princes of this world knew: for had they known it, they would not have crucified the Lord of glory.
I Corinthians 12:11-27:
But all these worketh that one and the selfsame Spirit, dividing to every man severally [his own] as he [the man] will.
For as the body is one, and hath many members, and all the members of that one body, being many, are one body: so also is Christ.
For by one Spirit are we all baptized into one body, whether we be Jews [Judeans] or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit.
For the body is not one member, but many.
If the foot shall say, Because I am not the hand, I am not of the body; is it therefore not of the body?
And if the ear shall say, Because I am not the eye, I am not of the body; is it therefore not of the body?
If the whole body were an eye, where were the hearing? If the whole were hearing, where were the smelling?
But now hath God set the members every one of them in the body, as it hath pleased him.
And if they were all one member, where were the body?
But now are they many members, yet but one body.
And the eye cannot say unto the hand, I have no need of thee: nor again the head to the feet, I have no need of you.
Nay, much more those members of the body, which seem to be more feeble, are necessary:
And those members of the body, which we think to be less honourable, upon these we bestow more abundant honour; and our uncomely parts have more abundant comeliness.
For our comely parts have no need: but God hath tempered the body together, having given more abundant honour to that part which lacked:
That there should be no schism in the body; but that the members should have the same care one for another.
And whether one member suffer, all the members suffer with it; or one member be honoured, all the members rejoice with it.
Now ye are the body of Christ, and members in particular.
Ephesians 1:22,23:
And hath put all things under his [Christ’s] feet, and gave him to be the head over all things to the church,
Which is his body, the fulness of him that filleth all in all.
Ephesians 3:2-6:
If ye have heard of the dispensation [administration] of the grace of God which is given me to you-ward:
How that by revelation he [God] made known unto me [the Apostle Paul] the mystery; (as I wrote afore in few words,
Whereby, when ye read, ye may understand my knowledge in the mystery of Christ)
Which in other ages was not made known unto the sons of men, as it is now revealed unto his holy apostles and prophets by the Spirit;
That the Gentiles should be fellowheirs, and of the same body, and partakers of his promise in Christ by the gospel.
Ephesians 5:22-32:
Wives, submit yourselves unto your own husbands, as unto the Lord.
For the husband is the head of the wife, even as Christ is the head of the church: and he is the saviour of the body.
Therefore as the church is subject unto Christ, so let the wives be to their own husbands in every thing.
Husbands, love your wives, even as Christ also loved the church, and gave himself for it;
That he might sanctify and cleanse it with the washing of water by the word,
That he might present it to himself a glorious church, not having spot, or wrinkle, or any such thing; but that it should be holy and without blemish.
So ought men to love their wives as their own bodies. He that loveth his wife loveth himself.
For no man ever yet hated his own flesh; but nourisheth and cherisheth it, even as the Lord the church:
For we are members of his body, of his flesh, and of his bones.
For this cause shall a man leave his father and mother, and shall be joined unto his wife, and they two shall be one flesh.
This is a great mystery: but I speak concerning Christ and the church.
Colossians 1:25-27:
Whereof I am made a minister, according to the dispensation [administration] of God which is given to me for you, to fulfil the word of God;
Even the mystery which hath been hid from ages and from generations, but now is made manifest to his saints:
To whom God would make known what is the riches of the glory of this mystery among the Gentiles; which is Christ in you, the hope of glory.
Colossians 2:10:
And ye are complete in him [Christ], which is the head of all principality and power.
Colossians 3:11-17:
Where there is neither Greek [Gentile] nor Jew [Judean], circumcision nor uncircumcision, Barbarian, Scythian, bond nor free: but Christ is all, and in all.
Put on therefore, as the elect of God, holy and beloved, bowels of mercies, kindness, humbleness of mind, meekness, longsuffering;
Forbearing one another, and forgiving one another, if any man have a quarrel against any: even as Christ forgave you, so also do ye.
And above all these things put on charity [the love of God], which is the bond of perfectness.
And let the peace of God rule in your hearts, to the which also ye are called in one body; and be ye thankful.
Let the word of [pertaining to] Christ dwell in you richly in all wisdom; teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord.
And whatsoever ye do in word or deed, do all in the name of the Lord Jesus, giving thanks to God and the Father by him.
