The paradox of Revelation

I read Graeme Goldsworthy's first chapter in The Gospel and Revelation. He explains the nature of Jewish apocalyptic literature. Common features include writing the secrets of a revelation (apocalpyse) from God onto a scroll which is sealed until the time for it to be revealed. He then points out how this plays out in Revelation 7 (see below): it is expected the mighty Lion of Judah will open the seal. But, instead the slain Lamb does! This illustrates the central paradox of the Gospel: the victory of God was not won by power but by the humiliation of his own Son.

⁶And between the throne and the four living creatures and among the elders I saw a Lamb standing, as though it had been slain, with seven horns and with seven eyes, which are the seven spirits of God sent out into all the earth. ⁷And he went and took the scroll from the right hand of him who was seated on the throne. ⁸And when he had taken the scroll, the four living creatures and the twenty-four elders fell down before the Lamb, each holding a harp, and golden bowls full of incense, which are the prayers of the saints. ⁹And they sang a new song, saying,

"Worthy are you to take the scroll
and to open its seals,
for you were slain, and by your blood you ransomed people for God from every tribe and language and people and nation,
