During His[Baha’u’llah’s] lifetime He was intensely active.
His energy was unlimited. Scarcely one night was passed in restful sleep. He
bore these ordeals, suffered these calamities and difficulties in order that a
manifestation of selflessness and service might become apparent in the world of
humanity; that the Most Great Peace should become a reality; that human souls
might appear as the angels of heaven; that heavenly miracles would be wrought
among men; that human faith should be strengthened and perfected; that the
precious, priceless bestowal of God—the human mind—might be developed to its
fullest capacity in the temple of the body; and that man might become the
reflection and likeness of God, even as it hath been revealed in the Bible,
“Let us make man in our image.” (‘Abdu’l-Baha, from a talk, 18 April 1912; ‘The Promulgation of Universal Peace: Talks
Delivered by 'Abdu'l-Bahá during His Visit to the United States and Canada in
1912’)
