The greater covenant refers to the covenant made between each messenger from God, which the literature of the Baháʼí Faith name Manifestations of God, and his followers regarding the coming of the next Manifestation from God. According to Baháʼu'lláh God has promised that he will send a succession of messengers that will instruct humankind. In Baháʼí belief, this covenant is seen to be expressed in prophecy in the religious scripture of each religion, and each Manifestation of God, such as Abraham, Moses, Jesus, Muhammad, the Báb, and Baháʼu'lláh, prophesied the next Manifestation. In return, the followers of each religion are seen to have a duty to investigate the claims of the following Manifestations.
