To me it means, man thinking he is greater, than God.
It means, to take, to control, to kill, to steal and destroy.
So, when it comes to actions of MAN, no weapon formed against the father, shall prosper.
Because, he is all I need, if your mind is so closed, that you think war is your answer, I pray that you have a moment when Gods reality hits YOU.
For no MAN, truly has control over anyone, its an ILLUSION in your mind, for everyone has a key, FREE WILL.
