Spirituality will defeat materialism

"Likewise didst thou ask whether, in this Baha'i Dispensation, the spiritual will ultimately prevail. It is certain that spirituality will defeat materialism, that the heavenly will subdue the human, and that through divine education the masses of mankind generally will take great steps forward in all degrees of life -- except for those who are blind and deaf and mute and dead. How can such as they understand the light? Though the sun's rays illumine every darkest corner of the globe, still the blind can have no share in the glory, and though the rain of heavenly mercy come down in torrents over all the earth, no shrub or flower will bloom from a barren land." Abdu'l-Baha, Selections from the Writings of Abdu'l-Baha
