The emphasis with which they affirm their conviction is remarkable: “We have believed and we know.” It is as if they felt, We may be doubtful of much and ignorant of much, but this at least we are sure of. We see men leaving our company who are fit to instruct and guide us in most matters, but they do not know our Lord as we do. What they have said has disturbed our minds and has caused us to revise our beliefs, but we return to our old position, “We have believed and we know.” It may be true that devils have been cast out by the prince of the devils; we do not know. But a stainless life is more miraculous and Divine than the casting out of devils; it is more unknown in the world, referrible to no freak of nature, accomplished by no sleight of hand or jugglery, but due only to the presence of God. Here we have not the sign or evidence of the thing but the thing itself, God not using man as an external agent for operating upon the material world, but God present in the man, living in his life, one with him.

Upon our faith nothing is more influential than the holiness of Christ. Nothing is more certainly Divine. Nothing is more characteristic of God—not His power, not His wisdom, not even His eternal Being. He who in his own person and life represents to us the holiness of God is more certainly superhuman than he who represents God’s power. A power to work miracles has often been delegated to men, but holiness cannot be so delegated. It belongs to character, to the man’s self; it is a thing of nature, of will, and of habit; a king may give to his ambassador ample powers, he may fill his hands with credentials, and load him with gifts which shall be acceptable to the monarch to whom he is sent, but he cannot give him a tact he does not naturally possess, a courtesy he has not acquired by dealing with other princes, nor the influence of wise and magnanimous words, if these do not inherently belong to the ambassador’s self. So the holiness of Christ was even more convincing than His power or His message. It was such a holiness as caused the disciples to feel that He was not a mere messenger. His holiness revealed _Himself_ as well as Him that sent Him; and the self that was thus revealed they felt to be more than human. When, therefore, their faith was tried by seeing the multitudes abandon their Lord, they were thrown back on their surest ground of confidence in Him; and that surest ground was not the miracles which all had seen, but the consecrated and perfect life which was known to them.
