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)?
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.
41 Isaiah said this because he saw His glory and spoke of Him. 42 And yet [in spite of all this] many even of the leading men (the authorities and the nobles) believed and trusted in Him. But because of the Pharisees they did not confess it, for fear that [if they should acknowledge Him] they would be expelled from the synagogue; 43 For they loved the approval and the praise and the glory that come from men [instead of and] more than the glory that comes from God. [They valued their credit with men more than their credit with God.]
