Answer: The meaning of the passage appears to be this: we do not know what to pray for as we ought, and therefore the grace of God gives us, not only an Advocate on high for us, but the Holy Ghost within us to identify Himself in grace with our sorrowing, suffering condition, so as to put us in fellowship with God as His redeemed ones in bodies withal and a creation not yet redeemed. He accordingly intercedes for us—within us of course—according to God, so as to give a divine and sympathetic character to what otherwise would have been but selfish sorrow. Thus we are entitled to know that our very groanings as Christians is not without the Spirit, though those cannot be expressed in words, and they rise up acceptable to God, and will be surely answered by the revelation of the glory by and by, for which we who have the first-fruits of the Spirit, and all creation also, wait. How sweet to think that the Holy Spirit, who gives and directs the joys of our hearts and makes us bid the bridegroom “come” (Rev. 22), takes equal part in our present griefs and travail of spirit! And if we do not know what to ask for, we do know that all things work together for good, as the apostle proceeds and proves so triumphantly to the end of the chapter.
