It was distinctive of the Son of Man that His Gospel was to be preached to the poor; and a system which addressed only minds capable of clear reasoning, could not be suited to all mankind; in fact, it would necessarily set up a Hierarchy of intellectual culture. So our Lord did not speak to the understandings but to the hearts of His hearers. He dealt with His disciples on the supposition, that there was in them a germ which would respond to the quickening influences of His teaching, and grow into a capacity for eternal life. Just as the dormant seed germinates when warmth and moisture reach it, so would what was dormant in their hearts burst into life and growth, when the required vivifying influence was brought to bear. Our spiritual life is made to depend not only on what is delivered to us, but on our recognising the truth we want, and seizing on it as what we are craving after: so that we say, “I have always felt that there was something I was in want of; now I know what it is, and I have it here.” The Jews, who would not believe, wanted to be shewn a Sign from Heaven. They said, “Give us a proof which is beyond contradiction, and we will believe,” which comes to saying: If we cannot help believing, believe we will. But they did not mean the same thing by the word “believe” as our Lord did. Our Lord did not call on His disciples to accept notions _about_ Him, but to believe _in_ Him, to trust Him as a child does his parent, or a soldier his commander. What the Jews meant was, that they would give credence to a particular kind of evidence, as to the fact of His being their Messiah.
