The head and members are of one nature, and not like that monstrous image that Nebuchadnezzar saw in his dream. The head was of fine gold, but the belly and thighs were of brass, the legs of iron, and the feet partly of iron and partly of clay. Christ's mystical body is no absurd combination of opposites. The members were mortal, and therefore Jesus died; the glorified head is immortal, and therefore the body is immortal too, as the record states: "Because I live, you also will live."1
As is our loving Head, so is His body, and every member in particular. A chosen Head, therefore chosen members; an accepted Head, therefore accepted members; a living Head, therefore living members. If the head is pure gold, all the parts of the body are pure gold also. There is a double union of nature as a basis for the closest communion.
Pause here, devout reader, and see if you can contemplate the infinite condescension of the Son of God in exalting your wretchedness into blessed union with His glory without being overwhelmed by the wonder of it. You are so feeble and poor that in remembering your mortality, you may say to decay, "You are my father," and to the worm, "You are my sister"; and yet in Christ you are so honored that you can say to the Almighty, "Abba, Father" and to the Incarnate God, "You are my Brother and my Husband."
Surely if relationships to ancient and noble families make men think highly of themselves, we have more cause to glory than all of them. Let the poorest and most despised believer take hold upon this privilege; do not let an unthinking laziness prevent him from tracing his pedigree, and do not let him focus so much on the here and now that he fails to think profitably of this glorious, heavenly honor of union with Christ.
