The issue of disobedience is consistently addressed throughout the course of the poem. The results of disobedience are clearly illustrated in book VI of the text. Raphael begins by describing a nonsense war to his listeners. Milton points out to the reader that the concept of war in Heaven is redundant simply because angels cannot die; they are only temporarily ruined.
"For spirits that live throughout
Vital in every part, not as frail man
In entrails, heart or head, liver or reins,
Cannot but by annihilating die" (VI: 344-347).
The fighting lasts for days. On the first day, Heaven’s angels are victorious because Michael’s sword has sliced though Satan’s right side:
"Descending, and in half cut sheer, nor stayed,
But with swift wheel reverse, deep entering sheared
All his right side; then Satan first knew pain" (VI: 325-328).
However, Satan’s wounds heal, and on the next day, Hell’s angels are victorious with the invention and implementation of the cannon. In response to this new fighting technique, Heaven’s angels lift up the hills and bury Satan’s army. However, the buried emerge from the entrapment and are prepared to fight on the third day. On the third day, God intervenes and announces the end of the war and the victory of Heaven. God states,
"Visibly, what by deity I am,
And in whose hand what by decree I do,
Second omnipotence, two days are past,
Two days, as we compute the days of heaven,
Since Michael and his powers went forth to tame
These disobedient; sore hath been their fight,
As likeliest was, when two such foes met armed;
For to themselves I left them, and thou know’st,
Equal in their creation they were formed,
Save what sin hath impaired, which yet hath wrought
Insensibly, for I suspend their doom;
Whence in perpetual fight they needs must last
Endless, and no solution will be found…
Two days are therefore past, the third is thine;
For thee I have ordained it, and thus far
Have suffered, that the glory may be thine.
Of ending this great war, since no one but thou
can end it" (VI: 682-703).
It is important to notice how God labels the opposing force as “these disobedient.” This directly addresses the subject of the text and implies that it is bad to disobey God. God explains both armies were equally formed, only one was impaired because of sin (disobedience); thus, God defines disobedience as a sin, a defect. In addition, God exerts his power by stating that he has held off the doom of the disobedient; further, only he has the power to end the war.
"Armed with thy might, rid heaven of these rebelled,
To their prepared ill mansion driven down
To chains of darkness, and the undying worm,
That from thy just obedience could revolt,
Whom to obey is happiness entire.
Then shall thy saints unmixed, and from the impure" (VI: 337-342).
Satan’s rebellion is pointless; he cannot emerge victorious. According to the text, there is no higher power than God. I'm not exactly sure of where I'm going with this, but I do think it is interesting to note the details that pertain to the concept of obedience/disobedience.
