I will close with a quote from the above book, "Salvation Applied By The Spirit: Union with Christ"-
"Jesus continues to speak of the same wonderful reality-this time expressed as the Father's and the Son's dwelling with believers-by using a different figure of speech. In John 14:1-3 he spoke of his preceding the disciples to heaven to prepare rooms for them in the Father's heavenly house. Now he returns to the image of a home but this time uses it of his and the Father's coming to the disciples to make their home with them on earth: "If anyone loves me, he will keep my word, and my Father will love him, and we will come to him and make our home with him" (v.23). Brown correctly states, "Here it ["dwelling place"] is used for the indwelling of the Father and the Son with the believer." And Kostenberger is right: "This is the only place in the NT where the Father and the Son are both said to indwell believers."
It is important to see the differences between the uses of "home" imagery in John 14:1-6 and verse 23. In the former passage Jesus goes ahead of the disciples to heaven to prepare a place for them in God's house. In the latter passage, the Father and the Son come to make their home with believers on earth. Carson captures the significance for our study:
My Father will love him, and we will come to him and make our home. . .with him. Thus, while Jesus leaves his disciples in order to prepare in his Father's house "dwelling places" (cf.v.2) for his followers, he simultaneously joins with the Father. . . making a "dwelling place" in the believer. Presumably this manifestation of the Father and the Son in the life of the believer is through the Spirit, although the text does not explicitly say so. Other New Testament passages testify to the dwelling of the Son in the Christian (e.g., Eph.3:17); this is the only place where the Father and Son are linked in this task. . . This is an anticipation, an inauguration of the final, consummating experience of God.
When Jesus departs, he will not leave his disciples as orphans. He will send them the Spirit, whom they will know, who will indwell them and be in them (vv.16-18). In addition, he will not leave them "homeless." Instead, the Father and the Son will come to "make their home" with believers. Jesus, then, employs this "homey" figure to reinforce his teaching on union. When Jesus ascends to the Father, the two of them will indwell God's people so that believers will experience the "immediate presence of Deity." . . ." pg.62,63 Robert A. Peterson
