In Revelation 10, John receives a vision of another strong angel with a little book in his hand. As he descends to earth, he puts one foot on land and one foot on the sea, reclaiming the kingdoms of the earth for Christ. John is then told to eat the little book, the book of God's final judgments upon the earth, which brings both joy and grief to his heart, which is the usual response of a true believer to God's judgment of sin.
