In the gospel of Luke at Chapter 11:50-51 (NIV), Jesus refers to Abel as a "prophet." I am not aware of any scripture spoken by Abel, which would prove that he is a prophet,but the words of Jesus clearly say,Abel is a prophet,as written in the gospel of Luke,
50 Therefore this generation will be held responsible for the blood of all the prophets that has been shed since the beginning of the world, 51 from the blood of Abel to the blood to the blood of Zechariah, who was killed between the altar and the sanctuary. Yes, I tell you, this generation will be held responsible for it all.
How is the reader meant to understand the reference that, "Abel is a prophet," when he has never spoken a prophetic word.?
