Paul, the Apostle, very clearly defines the generation that we live in at present...crooked and perverse. He also states how our status should be as believer's in the midst of such a generation...without blemish.
Even Jesus spoke about his desire as to how his disciples were to be....You are the light of the world. A city set on a hill can't be hid. Neither do you light a lamp, and put it under a bushel basket, but on a stand; and it shines to all who are in the house. Even so, let your light shine before men; that they may see your good works, and glorify your Father who is in heaven. (Matthew 5:14-16)
