O ye servants of the Blessed Beauty!... It is clear that in this day, confirmations from the unseen world are encompassing all those who deliver the divine Message. Should the work of teaching lapse, these confirmations would be entirely cut off, since it is impossible for the loved ones of God to receive assistance unless they teach.
(‘Abdu’l-Bahá, Selections from the Writings of ‘Abdu’l-Bahá, p. 264-265)
The confirmations of the Spirit are all those powers and gifts which some are born with (and which men sometimes call genius), but for which others have to strive with infinite pains. They come to that man or woman who accepts his life with radiant acquiescence.
(‘Abdu’l-Bahá, ‘Abdu’l-Bahá in London, p. 120)
Today the confirmations of the Kingdom of Bahá are with those who renounce themselves, forget their own opinions, cast aside personalities and are thinking of the welfare of others.
(‘Abdu’l-Bahá: Star of the West, Vol. XVII, p. 348)
Verily, thy Lord shall confirm thee in that which shall surprise the minds, through the glowing of its love and the manifestations of the signs of its favors.
(‘Abdu’l-Bahá, Tablets of ‘Abdu’l-Bahá v1, p. 111)
When the friends do not endeavour to spread the message, they fail to remember God befittingly, and will not witness the tokens of assistance and confirmation from the Bahá Kingdom nor comprehend the divine mysteries. However, when the tongue of the teacher is engaged in teaching, he will naturally himself be stimulated, will become a magnet attracting the divine aid and bounty of the Kingdom, and will be like unto the bird at the hour of dawn, which itself becometh exhilarated by its own singing, its warbling and its melody.
(‘Abdu’l-Bahá, Selections from the Writings of ‘Abdu’l-Bahá, p. 267-268)
You have read repeatedly in the Words of Bahá’u’lláh and ‘Abdu’l-Bahá that the confirmations and assistance of God will ever uninterruptedly descend upon you. While I was in Haifa visiting the Master there was one of the Oriental Bahá’ís who came and he was invoking and supplicating ‘Abdu’l-Bahá to give him confirmation and assistance. ‘Abdu’l-Bahá asked him: what is your mental picture, what is your conception regarding the confirmations of God? Do you think that the confirmations and assistance are objects which would be placed in a case or in a bag and sent down from heaven? This air, the infinite atmosphere with which we are surrounded is filled with invisible, innumerable hosts of confirmation. This expanse of the universe is overflowing with the spirit of God. These invisible armies of God are waiting file after file, rank after rank to see which soul will come into the arena of service, so that they may rush forward and reinforce him. No sooner a man arises, whether he lives in the east or the west or north or south, if he arises with sincerity, and steadfast attention and hope to spread the Cause of love to promote principles which are for the betterment of humanity, then those armies will descend upon his head. This man that you see serving, although outwardly he is alone and single, yet behind him there are invisible hosts of the Kingdom. You observe that a teacher, a Bahá’í, arises to teach, and apparently all the doors are closed before him, but suddenly the master key will be put into his hand and by these hosts all the doors will be opened. Outwardly he is ignorant but these invisible armies inspire him … If we arise with pure intention in the promotion of the Cause of God such confirmations will descend that we will be amazed and wonderstruck.
