In the Baha'i Faith, religious history is seen to have unfolded through a series of divine messengers, each of whom established a religion that was suited to the needs of the time and the capacity of the people. These Messengers have included Abraham, Buddha, Jesus, Muhammad and others, and most recently the Bab and Baha'u'llah. In Baha'i belief, each consecutive messenger prophesied of messengers to follow, Baha'u'llah's life and teachings fulfilled the end-time promises of previous scriptures. Humanity is understood to be in a process of collective evolution, and the need of the present time is for the gradual establishment of peace, justice and unity on a global scale.
