“I and My Father are one.” Then the Jews took up stones again to stone Him…”For a good work we stone Thee not; but for blasphemy; and because that Thou, being a man, makest Thyself God.”…”If I do not the works of My Father, believe Me not.” – John 10:30-31, 33, 37

Either our Lord was the Son of God, equal with the Father, or else He was an impostor, for He most distinctly claimed that He was the Son of God…Jesus said to the Jews, “If I honor Myself, My honor is nothing: it is my Father that honoureth Me; of whom ye say that He is your God.” Then they took up stones to cast at Him because He said that He was the Son of God…To believe in Christ merely as a prophet is not saving faith. It may be a step towards salvation, and it may lead up to it; but the faith that is absolutely necessary is that belief in Him as the Son of God; and he who does not believe in the Deity of Christ has not a Saviour who can save him. The work of saving a soul is a divine operation, and no one but a divine Being can accomplish it. It is He who sitteth upon the throne who saith, “Behold, I make all things new!” There cannot be anyone except the Creator who can create; and the Creator must, in every case, be God. To save a soul, there must be a work performed which is analogous to the resurrection; but, in order to raise the dead, there must be the presence and power of God. It is one of those operations which it is not conceivable that it can be performed by an angel or by any created being. The Highest alone can accomplish it; has He not said of Himself, “I kill, and I make alive”? The power of life and death must rest with God alone. Hence, then, the work of salvation needs a power nothing less than divine. He who believes in Christ as a mere man has not believed in a person who can give him salvation; and Christ cannot accomplish the stupendous task if He be only man, for the Saviour must be God.~ C.H.
