In Isaiah’s prophecy, there’s a reference to words in a scroll. But no one can read them because the scroll is sealed.
Later, God tells Daniel to take the words of his prophecy and seal it in a scroll until the end of time.
In Revelation, God gives John a scroll and tells him to open it. But John can’t because it’s sealed. He cries profusely because he sees no one worthy to open the seal. But there is one who can: Jesus. Jesus is worthy to break the seal and access the prophecy.
Later, as a final word, God tells John not to seal up his prophecy. The time is right; it must remain accessible.
In the Old Testament, scrolls are sealed. In the New Testament, Jesus breaks the seal. This is one more incredible connection between Old Testament prophecy and New Testament fulfillment.
