Is the city is Good? or Evil ?
God is good all the time, we are evil with original sin of disbelief and disobedience.  we are hositle and alienated from God.we are enemies to God and rebellious attitude. we are inwardly devilish and out wardly Godly.  we are created in the image of the Lord. and our inbuilt nature is sinful.
God said that you are to scatter whole earth, see and eat and live in harmony with the creator, but we always self esteemed, to make something special to prove ourselves that we are God. if man is apart from the Lord he lives in sin,dark,agony and destitute.
Man started making big towers to visualise from any long distance, so that they may come back. it is the very fear of losing themselves in the unknown world. we go aginst the command of God and make some  towns and cities. we find the inter personal ralations among the villagers than the city cluster people. they stay at one place without having any intimation with each other. some facilities  are available in the cities but unhealthy atmosphere.
