Material civilization needs to become “combined with Divine civilization”

And among the teachings of Bahá'u'lláh is that although material civilization is one of the means for the progress of the world of mankind, yet until it becomes combined with Divine civilization, the desired result, which is the felicity of mankind, will not be attained. (‘Abdu'l-Baha, 'Selections from the Writings of 'Abdu'l-Baha')
