Christ is risen, page-79

(Genesis 3:15) And I will put enmity between you and the woman and between your offspring and her offspring. He will crush your head, and you will strike him in the heel.”
(Genesis 22:18) And by means of your offspring all nations of the earth will obtain a blessing for themselves because you have listened to my voice.’”

That's part of the literal yarn according to a lot of theists.

(Galatians 3:16) Now the promises were spoken to Abraham and to his offspring. It does not say, “and to your descendants,” in the sense of many. Rather, it says, “and to your offspring,”
in the sense of one, who is Christ.
Here's the one that is soon to be fulfilled.(Revelation 20:1, 2) And I saw an angel coming down out of heaven with the key of the abyss and a great chain in his hand. 2 He seized the dragon, the original serpent, who is the Devil and Satan, and bound him for 1,000 years.

None of that is remotely literal and very much open to interpretation so I don't get where you are coming from.
