“And some of the Pharisees which were with him heard these words, and said unto him, Are we blind also?”
King James Version (KJV)
Joh 9:40,41 Are we blind also? The Pharisees ask this. They were not blind by necessity. They could see if they would. Hence they were responsible. Had they been without opportunity they would have no moral responsibility, but as they had opportunity to see and claimed to see, their "sin remaineth".
