The Bab prepared the way for Baha'u'llah as foretold. Baha'u'llah translated means "Glory of God", or "Glory of the Lord". The Bab (translated as Gate or door), They both came from Persia (Now part of Iran), East of the Holy Land.
Here is but one passages that mentions both these Revelations;
Ezekiel 43:1-5
1Then he led me to the gate, the gate facing toward the east;
2and behold, the glory of the God of Israel was coming from the way of the east. And His voice was like the sound of many waters; and the earth shone with His glory.
3And
it was like the appearance of the vision which I saw, like the vision which I saw when He came to destroy the city. And the visions
were like the vision which I saw by the river Chebar; and I fell on my face.
4 And the glory of the LORD came into the house by the way of the gate facing toward the east.
5And the Spirit lifted me up and brought me into the inner court; and behold, the glory of the LORD filled the house."
Christ means 'Annointed One' and that is how Christ is all Gods Messengers. They One and All are annointed of the same 'Holy Spirit', the "I Am", the 'Primal Will', the 'First and the Last', the 'Alpha and Omega'.
Baha'u'llah has started a Universal Cycle that will last at least 500,000 years. The next Messenger will come after a full 1000 years and this time is also confirmed by the Bible.
