If thou dost ponder a while, it will be evident that it is incumbent upon a lowly servant to acquiesce to whatever proof God hath appointed, and not to follow his own idle fancy.
(The Báb, Selections from the Writings of the Báb, p. 122)
The early believers in both the East and the West, we must always remember, knew practically nothing compared to what the average Bahá’í knows about his Faith nowadays; yet they were the ones who shed their blood, the ones who arose and said: ‘I believe‘, requiring no proof, and often never having read a single word of the Teachings. Therefore, those responsible for accepting new enrollments must just be sure of one thing—that the heart of the applicant has been touched with the spirit of the Faith. Everything else can be built on this foundation gradually.
