34 At this the people answered Him, We have learned from the Law that the Christ is to remain forever; how then can You say, The Son of Man must be lifted up [on the cross]? Who is this Son of Man? [Ps. 110:4.]
35 So Jesus said to them, You will have the Light only a little while longer. Walk while you have the Light [keep on living by it], so that darkness may not overtake and overcome you. He who walks about in the dark does not know where he goes [he is drifting].
36 While you have the Light, believe in the Light [have faith in it, hold to it, rely on it], that you may become sons of the Light and be filled with Light. Jesus said these things, and then He went away and hid Himself from them [was lost to their view].
37 Even though He had done so many miracles before them (right before their eyes), yet they still did not trust in Him and failed to believe in Him–
38 So that what Isaiah the prophet said was fulfilled: Lord, who has believed our report and our message? And to whom has the arm (the power) of the Lord been shown (unveiled and revealed)? [Isa. 53:1.]
39 Therefore they could not believe [they were unable to believe]. For Isaiah has also said,
40 He has blinded their eyes and hardened and benumbed their [callous, degenerated] hearts [He has made their minds dull], to keep them from seeing with their eyes and understanding with their hearts and minds and repenting and turning to Me to heal them.
