Race instinct, sense of nationality, enmity, and hatred, these are divisive forces between peoples. This is an astonishing punishment and a terrible judgment, and cannot be undone by any cosmopolitanism or leagues of peace, by any ‘universal’ language, nor by any world-state or international culture. If ever there is to be unity among mankind again it will not be achieved by any external, mechanical rallying around some tower of Babel or other, but by a development from within, a gathering under one and the same Head (Eph 1:10), by the peacemaking creation of all peoples into a new man (Eph 2:15), by regeneration and renewal through the Holy Spirit (Acts 2:15), and by the walking of all people in one and the same light (Rev 21:24).
