Here is a very good answer to this question by none other than Mr. Witness Lee:
Excerpt from The Spirit with Our Spirit
The Three of the Divine Trinity Coexisting and Coinhering as One God
The three of the Divine Trinity coexist and coinhere as one God from eternity to eternity (John 14:10-11, 26; 15:26; 10:30). Hence, He is the eternal God (Psa. 90:1-2). To coexist is to exist together at the same time. To coinhere is to mutually indwell one another. The Father exists in the Son and the Spirit, the Son exists in the Father and the Spirit, and the Spirit exists in the Father and the Son. This is coinherence. In John 14 the Lord Jesus Himself said that He is in the Father and the Father is in Him (vv. 10-11). The Lord also said that when He came from the Father, He came with the Father (8:16, 29; 16:32b). This means that when He comes, the Father comes in Him. Christ comes with the Father, and the Spirit comes with Christ (14:26; 15:26). The three are coinhering. The Lord Jesus also revealed that His speaking is the Father’s working (14:10). Thus, the Son’s speaking is the Father’s working, and the Spirit’s moving is the Son’s moving and the Father’s moving. The three not only coexist but also coinhere.

This answer to your question, my dear friend Raptor, is the coinherence of the three Persons of the Trinity. This is "how it works" with the indwelling of the Holy Spirit. Since Jesus Christ and the Holy Spirit indwell each other, or coinhere, Jesus Christ is in us through the indwelling of the Holy Spirit. At the most basic level, the Holy Spirit "represents" the Father and the Son. As I mentioned to Sons to Glory! there are certainly deeper and fuller understandings of the indwelling of the Holy Spirit, and I think those deeper and fuller understandings may be a topic for another thread.
