Union with Christ is the central doctrine of how God dwells with us. That union is the work of the Holy Spirit, sent from Christ’s throne in glory. We are not only united to Christ as our representative, living, dying and rising for us; we are also united to Christ vitally by the presence of His Spirit. He has not left us as orphans. He comes to us, and He dwells among us in our hearts and in our gatherings as His church.
