"The terminology of 'enemy' (echthros), 'enmity' (echthra), 'hate' (miseō) and its various related images must be seen within the context of the dualism of Pauline thought. Humanity is divided by Paul into 'those who are being saved' and 'those who are perishing' (1 Cor 1:18; 2 Cor 2:15); those of the kingdom of light and those of the domain of darkness (Col 1:12-13; cf. Gal 1:4); those who belong to Christ and those who belong to this world (Eph 2:1-10; 1 Cor 2:6-7). The backdrop for this division is the supernatural conflict between the rule of Christ and 'the spiritual forces of evil in the heavenly realms' (Eph 6:12; see Principalities and Powers). It is to the latter categories that the term enemy properly applies. . . ."
