Believers are called to become one with Jesus Christ and the Father, which is the destination Christ requests in John 17: "that they may be one as We are." God's goal, stated in I Corinthians 15:28, is to be all in all, with every member of His Family framed in His image and fully submissive to Him. Ephesians 1:22-23 shows Christ already filling all in all in relation to the church, which is His Body and His fullness. Each member is like a cell in that Body, linked to the Head, directed by Him, and placed where He pleases. The Father has given Him all authority in heaven and on earth, so He may use the church and any individual in it without asking permission. This is why He says, "Without Me you can do nothing" (John 15:5); fruit that glorifies God, and therefore a place in the Kingdom, depends on remaining joined to Him. His union with the church is as deep as that of husband and wife becoming one flesh (Ephesians 5), and His love can be counted on to carry members through to the Kingdom. The oneness is personal: the Father draws each member individually (John 6:44), as He personally chose the apostles. Being one with Christ means hearing Him above every other voice, as at the Transfiguration, and following His steps (I Peter 2:21). The Son and the Father are one, so when the Son speaks, the Father speaks.

We become spiritually unified with whatever we partake of. Because there is only one Bread of Life, who is Christ (John 6), everyone who shares in that One Bread becomes a single spiritual body. Paul illustrates the principle from physical Israel: those who ate of the sacrifices were partakers of the altar and so entered fellowship with the object of their worship. When Israelites ate from the altar of a false god, which means a demon, they joined in fellowship with that demon. Paul therefore says we cannot have it both ways: we either partake of the bread and wine, fellowshipping with Jesus Christ, or we participate in what demons offer, but never both. When an individual partakes of the cup of blessing and the bread at Passover, he becomes one with Christ. Because the whole church partakes of the same symbols, everyone who partakes becomes one with Him, and so with one another. The Lord's body is thus a collective noun, made up of those whom the Father called and who are now in fellowship with Christ through symbolically sharing in His blood and body. This oneness makes worthiness crucial. Those who mistreat, shame, or despise fellow members, for whom Christ died, and then take the Passover become guilty of Christ's body and blood, so each person must examine himself before partaking.

Our Father has called us into a true and faithful relationship with His beloved Son, Jesus Christ. As His future wife, He looks to us not only as a virgin who will always bring Him honor and respect, but also for a closeness on a level that becoming one flesh between a husband and a wife can only hint at on a spiritual plane. This is the essence of becoming one with Him. Jesus desires an intimate connection, akin to the profound unity described in human marriage, where true love, emotional desire, and mutual support foster a deep understanding. Our God has called us to be examples of the virtuous woman of Proverbs 31, reflecting this intimacy in our behavior and closeness to Him. Obedience to our God is vital, but it is this intimate closeness with our future Husband that He truly seeks, marking it as our ultimate purpose.
