2. He expected that His claim to have come forth from God would be believed _on His own word_. The Samaritans believed Him on His own word. This does not mean that they believed a mere assertion; they believed the assertion of One whom they felt to be speaking the truth. There was that in His character and bearing which compelled their faith. Through all He said there shone the self-evidencing light of truth. They might not have been able to stand a cross-examination as to the reason of the faith that was in them, they might not have been able to satisfy any other person or induce him to believe, but they were justified in following an instinct which said to them, This man is neither deceiver nor deceived. There was nothing in the claim of Jesus absolutely incredible. Nay, it rather fell in with their idea of God and with the knowledge of their own needs. They wished a revelation, and saw nothing impossible in it. This may nowadays be judged a homely rather than a philosophical view to take of God and of His relation to men. But primary and universal instincts have their place, and, if scientific knowledge does not contradict them, should be trusted. It was because the Samaritans had not tampered with their natural cravings and hopes, and had not allowed their idea of the Messiah to harden into a definite conception, that they were able to welcome Jesus with a faith which He rarely met with elsewhere.

And the main authentication of Christ’s claim at all times is simply this, that He makes the claim, and that there is that in Him which testifies to His truth, while there is that in the claim itself which is congruous to our instincts and needs. There was that in the bearing of Christ which commanded belief in natures which were not numbed and blunted by prejudice. The Capernaum courtier who came to Jesus expecting to bring Him down with him to heal his boy, when he saw Him felt he could trust Him, and returned alone. Jesus was conscious that He spoke of what He knew, and spoke of it truly. “I speak that which I have seen with My Father” (ver. 38). “My record is true” (ver. 14). “If I say the truth, why do ye not believe Me?” (ver. 46.) This consciousness, both of an intention to speak the truth and of a knowledge of the truth, in a mind so pellucid and sane, justly impressed candid minds in His own day, and is irresistibly impressive still.
