They said therefore to him, "What then do you do for a sign, that we may see, and believe you? What work do you do?
      First,  We shall be  one with Christ,  as our bodies are with our food when it is digested (; John 6:56):  He that eats my flesh, and drinks my blood,  that lives by faith in Christ crucified (it is spoken of as a continued act), he  dwelleth in me, and I in him.  By faith we have a close and intimate union with Christ; he is  in us,  and we  in him,  John 17:21-23; 1 John 3:24. Believers dwell in Christ as their stronghold or city of refuge; Christ dwells in them as the master of the house, to rule it and provide for it. Such is the union between Christ and believers that he shares in their griefs, and they share in his graces and joys; he  sups  with them upon their bitter herbs, and  they with him  upon his  rich dainties.  It is an inseparable union, like that between the body and digested food,  ; Romans 8:35; 1 John 4:13.
