References for Matthew 13:10
Jesus replied, “Because they haven't received the secrets of the kingdom of heaven, but you have.

For this people's senses have become calloused, and they've become hard of hearing, and they've shut their eyes so that they won't see with their eyes or hear with their ears or understand with their minds, and change their hearts and lives that I may heal them.
References for Matthew 13:15

I assure you that many prophets and righteous people wanted to see what you see and hear what you hear, but they didn't.
