'Of the World' in the Bible

According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love:

for the government of the world when the times are ripe for it--the purpose which He has cherished in His own mind of restoring the whole creation to find its one Head in Christ; yes, things in Heaven and things on earth, to find their one Head in Him.

In which at one time ye walked, according to the age of the world, according to the prince of the authority of the air, of the spirit that now energiseth in the sons of disobedience,

And to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ:

For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the world, of the darkness of this age, against wicked spirits in heavenly places.
