The resurrection of the body is very important to understand. We are these bodies, we are dust. These living bodies of dust are called "souls." We are dust and our hope of immortality rests in the hope of being raised from the dead out of the dust of the earth unto eternal life and gathered to Jesus Christ at his coming.
Our resurrection bodies will be like Jesus' resurrection body. We will bear the image of the man of heaven, that is, the risen Jesus. Jesus' risen body is described by Paul as "life-giving Spirit." It is a body which is swallowed up in victory, swallowed up in life. That life is the Holy Spirit. The Spirit is life. The Spirit consumes these mortal bodies unto life. The resurrection body is a mortal body consumed in immortality, that is, consumed by the Spirit of God. It is a fleshly body consumed in the Holy Spirit of God. It is a fleshly body clothed in the Holy Spirit of God and as such it is no longer naked by clothed in God's glory. Those who have the Spirit of God in them now have the Spirit as a pledge from God of this resurrection hope.
Our resurrection body is where the Spirit and our physical bodies become one new creation. But it is not as if this new creation has a horizon between the Spirit and our mortal bodies such that we can discern two things. The resurrection body is a new creation where the two have become one, the Spirit and physical humanity becoming one new thing, a divine humanity. In this way, these selfsame bodies are "Spiritual" bodies because they will be consumed and clothed in the Holy Spirit of God. We are those who yield up our bodies as living sacrifices. In the resurrection, God consumes his sacrifices but not unto destruction; He consumed us, these bodies, unto life. We will be consumed and enveloped in the love and glory of God forever.
