“The only reason they didn’t believe is because they choose not to.”
Well, like I said, I can only speculate, but the verses I posted show God had some involvement in making some people blind to the truth of Jesus. Perhaps the “hardening” of their hearts was only temporary, so that the task of Jesus would be accomplished according to God’s will, kind of like Pharoah’s heart was hardened temporarily during the Exodus.
But, there are examples of people who recognized the miracles, and joined with the Christians, but didn’t truly believe after all. Just look at Simon Magus. God certainly would know in advance that people like Simon might have some semblance of faith but not truly believe.
