The Family Resemblance

Have you ever seen someone you may not know, but you immediately know who they're kin to, because of some physical trait or characteristic they possess? Maybe it's the way they laugh, or the way they walk; or some other physical marker that identifies them, whether they like it or not, as belonging to a specific family? In that same way, Gods children should possess and reflect His characteristics; traits that should be recognizable by others as identifiers of who's family we belong to.
