Concerning the family of Christ, the Church is the bride of Christ because just as a bride and groom become one when married, we become one with Christ when we receive His Holy Spirit.
Eph 1: 10 That in the dispensation of the fullness of times He might gather together in one all things in Christ, both which are in heaven, and which are on earth, even (that is) in Him;
Eph 1: 22-23 And hath put all things under His feet, and gave Him to be the head over all things to the Church, Which is His body, the fullness of Him that filleth all in all.
When we receive the Holy Spirit of the Father and Son (both reside in our hearts), we become part of the spiritual body of Christ as well as adopted children of the Father. We are in Christ and Christ is in us. The Father is in Christ because Christ is filled with the Father's Spirit and therefore is a temple for the Father just as we are.
John 17: 21 That they all may be One, as thou, Father, art in me, and I in Thee, that they also, may be One in us; ..... And the glory (Father's Spirit) which thou gavest me I have given them, that they may be one, even as we are one: I in them, and thou in me that they may be made perfect in One; and that the world may know that thou hast sent me, and hast loved them, as thou hast loved me Eph 2: 19 .Now, therefore, ye are no more strangers and sojourners, but fellow citizens with the saints, and of the household of God;
Eph 4: 10- 16 He that descended is the same also that ascended up far above all heavens, that he might fill all things. And He gave some apostles; and some, prophets; and some, evangelists; and some, pastors and teachers; For the perfecting of the saints for the work of the ministry for the edifying of the body of Christ, Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fullness of Christ; That we henceforth be no more children tossed to and fro, and carried about with every wind of doctrine, by the sleight of men, and cunning craftiness, by which they lie in wait to deceive; But, speaking the truth in love, may grow up into Him in all things, who is the head, even (that is) Christ; From whom the whole body fitly joined together and compacted by that every joint supplieth, according to the effectual working in the measure of every part, maketh increase of the body unto the edifying of itself in LOVE.
When Christ went back to heaven to get glorified by the Father, He was given an empty spiritual body and the Father's Holy Spirit to fill His body with. That is when Christ sent the Comforter (the Spirit of the Father and Christ) in order to fill His spiritual body with the Father's Spirit joined to ours. We as members of God's family want to assist in edifying Christ's body through sharing in the knowledge of the Truth in Love.
John 17: 3 And this is life eternal, that they might know thee, the only true God, and Jesus Christ, whom thou hast sent.
Matt 11: 25-27 No man knoweth the Father except the Son and to whomsoever the Son will reveal Him.
