This is a challenging chapter! Let’s remember that there is much figurative language in Revelation. Instead of trying to figure out the specific meaning of each image look for the general ideas.
The chapter begins with Satan being bound for 1000 years. Remember, Satan’s allies in the conflict with the churches (the beasts) were cast into the Lake of fire at the end of chapter 19, but Satan is bound for 1000 years, and then will be released. What does he do when he is released? (7-9).
What becomes of Satan after that? (10)
What one last event is recorded in this chapter? (11-15).
What is the second death?
Thought for the day: Everyone will die once, but how can we be sure we will not be a part of the second death? See also, 21:8.
