…the evolution of the World Order of Bahá'u'lláh is an organic process proceeding in accordance with the Divine Will and animated by a spiritual reality. In response to a question, ‘Abdu'l-Bahá wrote:

"The kingdom of peace, salvation, uprightness, and reconciliation is founded in the invisible world, and it will by degrees become manifest and apparent through the power of the Word of God!"

As a result of consecrated human endeavour over decades, and indeed centuries, this spiritual reality is gradually expressed in physical form.
