Intercessory prayer is more than just praying for someone... it is praying with them; it is praying the needs and desires of someone who might be in a coma using the words and supplication that we would pray with them if they were able to hold our hands and pray alongside us... it remains a joint prayer as we ask for God's intercession in a situation or life. It is being with someone who might be silent, but who prays with us in the presence of God. Isn’t this exactly what the Holy Spirit does when he prays for us in groanings which we alone cannot utter; at times when we have no words?
