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?
      [1.] He assures us, in general, that he came from heaven upon his Father's business (; John 6:38), not  do his own will, but the will of him that sent him.  He  came from heaven,  which bespeaks him an intelligent active being, who voluntarily descended to this lower world, a long journey, and a great step downward, considering the glories of the world he came from and the calamities of the world he came to; we may well ask with wonder, "What moved him to such an expedition?" Here he tells that he came to do, not  his own will,  but the will of his Father; not that he had any will that stood in competition with the will of his Father, but those to whom he spoke suspected he might. "No," saith he, "my own will is not the spring I act from, nor the rule I go by, but I am come to  do the will of him that sent me." That is,  First,  Christ did not come into the world as a  private  person, that acts for himself only, but under a  public character,  to act for others as an ambassador, or plenipotentiary, authorized by a public commission; he came into the world as God's great agent and the world's great physician. It was not any private business that brought him hither, but he came to settle affairs between parties no less considerable than the great Creator and the whole creation.  Secondly,  Christ, when he was in the world, did not carry on any  private  design, nor had any  separate interest  at all, distinct from theirs for whom he acted. The scope of his whole life was to glorify God and do good to men. He therefore never consulted his own ease, safety, or quiet; but, when he was to lay down his life, though he had a human nature which startled at it, he set aside the consideration of that, and resolved his will as man into the will of God:  Not as I will, but as thou wilt.
