Progressive revelation is a core teaching in the Baháʼí Faith that suggests that religious truth is revealed by God progressively and cyclically over time through a series of divine Messengers, and that the teachings are tailored to suit the needs of the time and place of their appearance.
In this respect, each Manifestation of God hath a distinct individuality, a definitely prescribed mission, a predestined revelation, and specially designated limitations. Each one of them is known by a different name, is characterised by a special attribute, fulfils a definite mission, and is entrusted with a particular Revelation.
Bahá’u’lláh
The coming of each new messenger and the teachings they bring is compared to the coming of Spring, as the teachings bring new life to the world. Baháʼís accept the founders of the “major world religions” as Manifestations of God. The usual list Baháʼís commonly refer to include Krishna, Buddha, Zoroaster (Zarathustra), Abraham, Moses, Jesus, Muhammad, the Báb, and Baháʼu’lláh.
Among the bounties of God is revelation. Hence revelation is progressive and continuous. It never ceases. It is necessary that the reality of Divinity with all its perfections and attributes should become resplendent in the human world. The reality of Divinity is like an endless ocean. Revelation may be likened to the rain. Can you imagine the cessation of rain? Ever on the face of the earth somewhere rain is pouring down.
