Hmmm... having a little technical problem with the reply box...
Anyway, 1 - 3 is about the world conspiring against God
4 - 9 is about God scoffing at them, saying He's installed His own Son to break their rule and take the world as an inheritance
10 - 12 exhorts the kings and rulers to take the hint and turn to God, lest his wrath be upon them.
Does that help?
