Jesus Said, "I say!!"

Commenting on Jesus' sermon on the mount (Matthew 5-7), J. Gresham Machen wrote:

"For what prophet ever spoke in this way? The prophets said, 'Thus saith the Lord,' but Jesus said, 'I say.' We have no mere prophet here, no mere humble exponent of the will of God; but a stupendous Person speaking in a manner which for any other person would be abominable and absurd."
