John states that the New Jerusalem will be free of sin. The servants of God will have theosis (i.e. the power or likeness of God, that is "in his image" of holiness) and "His name will be on their foreheads." Night will no longer fall, and the inhabitants of the city will "have need (of) no lamp nor light of the sun, for the Lord God gives them light." John ends his account of the New Jerusalem by stressing its eternal nature: "And they shall reign forever and ever."
