As far as possible, rest thou not for a moment, travel to the North and South of the country and summon all men to the oneness of the world of humanity and to universal peace, saying: O people! Bahá’u’lláh laid the foundation of universal peace fifty years ago. He even addressed Epistles to the kings wherein He declared that war could destroy the foundation of the world of humanity, that peace is conducive to everlasting life and that dire peril awaited mankind. Also three years before the outbreak of the world war ‘Abdu’l-Bahá travelled to America and most of Europe, where he raised His voice before all gatherings, societies and churches, appealing: O ye assemblage of men! The continent of Europe hath virtually become an arsenal filled with explosives. There are vast stores of destructive material hidden underground, liable to burst forth at a single spark, causing the whole earth to quake. O ye men of understanding! Bestir yourselves that perchance this accumulation of volatile material may not explode. But the appeal went unheeded and consequently this murderous war broke out.
