Matthew 7:28 And so it was, when Jesus had ended these sayings, that the people were astonished at His teaching,
29 for He taught them as one having authority, and not as the scribes.
Anyone can repeat or read off a script. Jesus speaks a heartfelt and life giving message. What He says, every single word, has impact and purpose. He shares words of meaning. There are no idle words spoken by Jesus. He teaches with authority because He is the Word of authority. The scribes could only quote, at best, a third party source. They had zero heart behind the meanings of what they taught about. They focused on the letter of the law and not on the Spirit. Last but not least, Jesus spoke with LOVE and grace everytime. I am to this day amazed when I hear the LORD speak.
