Revelation 22:10

John received instruction from the angel to leave his book open. He was not to close it because the fulfillment of the events predicted was near, and people needed to be aware of them (cf. Revelation 1:11). God had told Daniel to seal his prophecy, evidently because there was more prophecy to come (Daniel 8:26; Daniel 12:4; Daniel 12:9-10; cf. Revelation 10:4). As an artist covers his work when it is under construction until it is complete, so God covered His picture of the future until He finished it.
