3. John notes the insufficient tests used both by the people and by the authorities for ascertaining whether Jesus was or was not their promised King. The tests they used were such as these, “Will Christ do more miracles?” “Will He come from the same part of the country?” and so forth. Among ourselves it has become customary to speak as if it were impossible to find or apply any sufficient test to the claims of Christ; impossible to ascertain whether He is, in a peculiar sense, Divine, and whether we can absolutely trust all He said, and accept the views of God He cherished and proclaimed. Certainly Christ Himself does not countenance this mode of speaking. In all His conversations with the unbelieving Jews He condemned them for their unbelief, ascribed it to moral defects, and persistently maintained that it was within the reach of any man to ascertain whether He was true or a pretender. There is a class of expressions which occur in this Gospel which clearly show what Jesus Himself considered to be the root of unbelief. To Pilate He says, “Every one that is _of the truth_ heareth My voice.” To the Jews He says, “He that is of God, heareth God’s words; ye therefore hear them not, because ye are not of God.” And again in this seventh chapter, “If any man is desirous to do the will of God, he will know of My doctrine whether it be of God, or whether I speak of Myself.” All these statements convey the impression that Christ’s person and teaching will uniformly be acceptable to those who love the truth, and who are anxious to do the will of God.
