Consider ... the revelation of the light of the Name of God, the Educator. Behold, how in all things the evidences of such a revelation are manifest, how the betterment of all beings dependeth upon it. This education is of two kinds. The one is universal. Its influence pervadeth all things and sustaineth them. It is for this reason that God hath assumed the title, "Lord of all worlds". The other is confined to them that have come under the shadow of this Name, and sought the shelter of this most mighty Revelation. They, however, that have failed to seek this shelter, have deprived themselves of this privilege, and are powerless to benefit from the spiritual sustenance that hath been sent down through the heavenly grace of this Most Great Name. How great the gulf fixed between the one and the other!... (Baha’u’llah, ‘Gleanings from the Writings of Bahá'u'lláh’; The Compilation of Compilations, vol. I, Baha’i Education)
