John 12:38-41

38This showed that the prophet Isaiah had spoken true words when he said: ‘Lord, has anyone believed our message? You have shown how powerful you are, but nobody has really understood.’

39Isaiah spoke also about why the people could not believe.

40He said: ‘God has made their eyes unable to see. He has closed their minds. So they cannot see with their eyes, and they cannot understand with their minds. They will not turn to me, so that I can make them well.’

41Long ago, Isaiah saw the great glory of Christ. That is why he said these things. He was speaking about Jesus.
