Ezekiel, like all the prophets of the Old Testament, was given God’s Word to tell to God’s people. The call of the prophets was to foretell and forth-tell, meaning that they told of the future, but also spoke forth God’s Word to God’s people in their present circumstances and context.
This is pictured in the book of Ezekiel when Ezekiel is shown a scroll, upon which were the complete words of God for him to speak. He was to eat this scroll, figuratively, or to take all of God’s words into himself so that he could understand them and then speak them from what was inside him. John was told to do the same in Revelation (10:8-11).
These prophets were told to eat in order to have God’s words in them, but Jesus is the Word, made flesh. “And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth” (John 1:14). He did not need to eat, for he was already the Word of God, given so that others could tell about him. All the prophets pointed forward to the Prophet beyond compare, Jesus. Rejoice that Jesus came to be God’s Word in the flesh, and to take away our sins so that he could bring us to God.
