Chapter 10 is filled with Old Testament images and allusions that are re-appropriated to the context of the Roman Empire. To fully understand the command to 'eat the scroll' we need to turn back to the Book of Ezekiel- specifically Chapters 2 and 3. 600 years before Christ -Ezekiel is told to eat a scroll which would taste like honey to his lips. This command is designed to show that Ezekiel must internalize the message. In Revelation Chapter 10, God gives John the same command: 'eat the scroll!'
Revelation Chapter 10 tells us that John will deliver a message that will be both pleasing and disturbing. This is the great truth of God's Word: it is both a message of hope and foolishness. The message of the Cross is sweet. Freedom from past sins, redemption, forgiveness -all provided by Christ. And at the same time the message of the Cross is bitter. I must die to myself, surrender everything and allow Christ first-place in my life. This is a difficult pill to swallow.
