'Of This World' in the Bible

where is the wise? where is the scribe? where is the disputant of this age? has not God prov'd the wisdom of this world to be downright folly.

now the spirit which we have received, is not the spirit of this world, but that which comes from God; that we might know what he has graciously bestowed upon us.

for the wisdom of this world is folly, in the eye of God: as it is written, "he surprizes the wise in all their artifices."

and they that possess this world, as those that can't make an ill use of it. for the scene of this world is continually shifting. I would have you free from anxiety.
