I anticipate many of us are troubled by John 12:37-42.

37 Even after Jesus had performed so many signs in their presence, they still would not believe in him. 38 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 could not believe, because, as Isaiah says elsewhere:

40 “He has blinded their eyes
    and hardened their hearts,
so they can neither see with their eyes,
    nor understand with their hearts,
    nor turn—and I would heal them.”

41 Isaiah said this because he saw Jesus’ glory and spoke about him.

42 Yet at the same time many even among the leaders believed in him. But because of the Pharisees they would not openly acknowledge their faith for fear they would be put out of the synagogue; 43 for they loved human praise more than praise from God.

Why didn’t more of the Jews believe in Jesus?

When Isaiah the prophet was called by God (around 700 B.C.), God tells him to expect constant rejection from his people. So, when John reflects on the ministry of Jesus, he remembers that Isaiah was also rejected. In fact, the rejection was so complete that it was as if God had hardened the hearts of the Israelites to make it impossible for them to respond. Now, why would God set Isaiah up to fail? That’s the wrong way to think about it; it’s not that God set Isaiah up to fail, but that God knew that Isaiah’s ministry would be very difficult, and that though Israel would not listen, Isaiah is to preach to them anyway.

In the same way, Jesus came performing many signs and many people still refused to accept him. It’s as if God has hardened their hearts—why else would they refuse to believe?

But, John also tells us that the rejection was not total; actually, there were many people who believed, and some believed secretly.

So, John wants us to understand that the mighty works of Jesus were not enough to convince everyone of his identity. Some people were so stubborn that nothing would make them believe: it was as if God made their hearts hard and eyes blind.

I think this means 2 things for us:

1. We should not be surprised when people in our day reject Jesus.

2. But, we should also expect people to accept him in our day.

How can you tell which group is which?

You can’t—you have to sow the seed as widely as possible with the expectation that though it might not take root everywhere, it will take root somewhere.
