Paul gets to explain his gospel to the Jewish community in Rome, and here’s what he said:

so that they would not see with their eyes
and hear with their ears
and understand with their heart
and turn, and I would heal them.“‘
28:28 “Therefore be advised that this salvation from God has been sent to the Gentiles; they will listen!”
