Each stage of the Bahá'í Faith's development has unfolded according to the needs of the time, building upon what has come before and laying the groundwork for the next phase of its evolution. Each has challenged the Bahá'ís to attain a more profound understanding of Bahá'u'lláh's Revelation and the practical steps required for the eventual transformation of the world. And each has yielded a more united community, possessed of greater clarity of thought about the means to achieve His vision for humanity, and greater capacity to act accordingly.
