We do not live in a perfect world, because sin ravage it.
A perfect world would be full of peace and love for all.
It would mean that there would be no poor people either.
It would mean no sickness nor homelessness nor pain.
It would mean that we would all love one another.
It would mean no death , just life full of unconditional love.
But we do not live in a perfect world yet not till Christ returns.
Then it shall be the true Perfect World for all whom belong to him.
