Charles Spurgeon Commentary John 12:34-41

"The multitude therefore answered him, We have heard out of the law that the Christ abideth for ever: and how sayest thou, The Son of man must be lifted up? who is this Son of man? Jesus therefore said unto them, Yet a little while is the light among you. Walk while ye have the light, that darkness overtake you not: and he that walketh in the darkness knoweth not whither he goeth. While ye have the light, believe on the light, that ye may become sons of light. These things spake Jesus, and he departed and hid himself from them. But though he had done so many signs before them, yet they believed not on him: that the word of Isaiah the prophet might be fulfilled, which he spake, Lord, who hath believed our report? And to whom hath the arm of the Lord been revealed? For this cause they could not believe, for that Isaiah said again, He hath blinded their eyes, and he hardened their heart; Lest they should see with their eyes, and perceive with their heart, And should turn, And I should heal them. These things said Isaiah, because he saw his glory; and he spake of him." — John 12:34-41 (ASV)

We have heard out of the law that Christ abideth forever: and how sayest thou, The Son of man must be lifted up? who is this Son of man? Then Jesus said unto them, Yet a little while is the light with you. Walk while ye have the light, lest darkness come upon you: for he that walketh in darkness knoweth not whither he goeth.

While ye have light, believe in the light, that ye may be the children of light. These things spake Jesus, and departed, and did hide himself from them. But though he had done so many miracles before them, yet they believed not on him: that the saying of Esaias the prophet might be fulfilled, which he spake, Lord, who hath believed our report? and to whom hath the arm of the Lord been revealed?

Therefore they could not believe, because that Esaias said again, He hath blinded their eyes, and hardened their heart; that they should not see with their eyes, nor understand with their heart, and be converted, and I should heal them. These things said Esaias, when he saw his glory, and spake of him.

It is a terrible thing to resist the Spirit of God, for if His softening influences are withdrawn, the heart grows hard; if His enlightening influences are taken away, the eyes of the understanding are darkened. I do believe there are many who have so long trifled with conscience and violated the best instincts of their nature that they are given up as those who are past hope. I pray God that it may not be so with any here; but it was so with many in the generation among whom Christ labored.
