Little Book

  1. And I saw another mighty angel come down from heaven, clothed with a cloud: and a rainbow was upon his head, and his face was as it were the sun, and his feet as pillars of fire:
  2. And he had in his hand a little book open: and he set his right foot upon the sea, and his left foot on the earth,

Who is the mighty angel?

The mighty angel who instructed John was no less a personage than Jesus Christ. Setting His right foot on the sea, and His left upon the dry land, shows the part which He is acting in the closing scenes of the great controversy with Satan. This position denotes His supreme power and authority over the whole earth. The controversy has waxed stronger and more determined from age to age, and will continue to do so, to the concluding scenes when the masterly working of the powers of darkness shall reach their height. Satan, united with evil men, will deceive the whole world and the churches who receive not the love of the truth. But the mighty angel demands attention. He cries with a loud voice. He is to show the power and authority of His voice to those who have united with Satan to oppose the truth. After these seven thunders uttered their voices, the injunction comes to John as to Daniel in regard to the little book: “Seal up those things which the seven thunders uttered” (Revelation 10:4). These relate to future events which will be disclosed in their order. Daniel shall stand in his lot at the end of the days. John sees the little book unsealed. Then Daniel's prophecies have their proper place in the first, second, and third angels’ messages to be given to the world. The unsealing of the little book was the message in relation to time. 1MR 99.1

This little book was the book of Daniel, which is the "sealed book" Daniel 12:4.

4. But thou, O Daniel, shut up the words, and seal the book, even to the time of the end: many shall run to and fro, and knowledge shall be increased.

8. And the voice which I heard from heaven spake unto me again, and said, Go and take the little book which is open in the hand of the angel which standeth upon the sea and upon the earth.
9. And I went unto the angel, and said unto him, Give me the little book. And he said unto me, Take it, and eat it up; and it shall make thy belly bitter, but it shall be in thy mouth sweet as honey.

The little book which is now open refers to the book of Daniel. While Daniel 8:14 points to the fulfillment of the 2300 days prophecy, terminated in 1844, which resulted in the Great Disappointment experience depicted by bitterness in the belly.
