Our Two Intercessors

Continuing reflection on Romans 8 and particularly the intercession of the Spirit.
Romans 8 is a passage about eschatological tension, and our groaning flows out of looking forward to the glorious hope of the revelation of the sons of God.
The groans of the Spirit are an acceptable prayer to the Father, because they express our eschatological yearning, for Christ to return, for our adoption, for our freedom and for our redeemed bodies. It is a forward looking prayer, concerning ultimately the work of the Spirit Himself, namely our uniting to Christ, our sanctification and the renewal of all things. It is a prayer from earth, because the Spirit is with and in us.
Contrast that with the heavenly intercession of Christ: not on earth, but before heaven's throne. Although I can't find where John Owen gets it from, he argues that it is also unspeaking, the showing of His Calvary wounds; that would be an interesting half-similarity, half-difference to the Spirit's groans. Christ's intercession is also not forward, but backward-looking, looking back to Calvary, to redemption not future but past and complete. And like the Spirit's intercession concerned the Spirit's work, so Christ's intercession concerns His own work.
In this intercession we see therefore the communion of Father, Son and Holy Spirit, each in their common cause and in their genuine trialogue concerned for their own ministry to bring glory to the unity. And we see how dependent we are on a sovereign Trinity to save us: for without Christ's intercession, why should we benefit from His Cross, and given that we don't know how to pray in line with God's will (Romans 8:26), without the Spirit's intercession, how would we make any progress in the Christian life?
Praise God, Father, Son and Holy Spirit, our saving Trinity, for their pursuit of their own glory in the demonstration of their saving grace and power!
