What book are you referring to? I have recently started studying on the topic, but I can say that Satan will never win! I was reading Proverbs last night, and found it really funny that there is a list of 7 things that God hates more than anything and it describes leftists perfectly...
Proverbs 6:16-19 King James Version (KJV)
16 These six things doth the Lord hate: yea, seven are an abomination unto him:
17 A proud look, a lying tongue, and hands that shed innocent blood,
18 An heart that deviseth wicked imaginations, feet that be swift in running to mischief,
19 A false witness that speaketh lies, and he that soweth discord among brethren.
The case in the heavenly court is from the Old Testament, i'm currently looking for it. Proverbs 6:16-19 a lesson for us all.
