They that have forsaken their country for the purpose of teaching Our Cause -- these shall the Faithful Spirit strengthen through its power. A company of Our chosen angels shall go forth with them, as bidden by Him Who is the Almighty, the All-Wise. How great the blessedness that awaiteth him that hath attained the honor of serving the Almighty!
(Baha’u’llah, ‘Gleanings from the Writings of Bahá'u'lláh’; The Compilation of Compilations, vol. II, The Power of Divine Assistance)
