again, according to the Bahai faith, all the religions have two (at least) levels of messages. One, the spiritual truth, never changes, and
the other message is the one brought by prophets, with a social message which adapts to the times, and the conditions of the humans on the planet. They say that prophets must come to Earth when the people need to hear a new message, or have another reminder of the divine truth.

They recognize several divine messengers, which all act as mirrors to reflect the pure light of truth.

This concept is called Progressive Revelation. They say that humans can only "touch the hem of the garment" of God, and are not capable of understanding all there is to know about God, because we are not "great" enough to see or know the whole picture.
