John 12:38

36 While you have the Light, believe in the Light, so that you may become sons of light.” After Jesus had spoken these things, He went away and was hidden from them.

37 Although Jesus had performed so many signs in their presence, they still did not believe in Him.

This was to fulfill the word of Isaiah the prophet: “Lord, who has believed our message? And to whom has the arm of the Lord been revealed?”

39 For this reason they were unable to believe. For again, Isaiah says:

40 “He has blinded their eyes and hardened their hearts, so that they cannot see with their eyes, and understand with their hearts, and turn, and I would heal them.”

Here the Bible tells a story about someone else. Ask yourself what it can say to us today. Do read the surrounding verses too, because the context often says more than a single verse.
