Natural (5446) (phusikos from phúsis = nature) (only 3 NT uses - Ro 1:26, 27; 2Pe 2:12) means pertaining to things in accordance with nature or belonging to the naturally regulated order of things. Phusikos refers to those things which one does out of instinct. The idea is that something pertains to that which is in accordance with the nature or character of that thing. Thus it is natural for both men and woman to desire heterosexual relationships. Peter uses phusikos to describe false teachers as likened to animals whose natural destiny is to be victims of predators.
