If Daniel 7:14,15 refers to Baha'u'llah, it's odd that he isn't mentioned in Philippians 2:9,10:
'Wherefore God also hath highly exalted him, and given him a name which is above every name:
That at the name of Jesus [not Baha'u'llah] every knee should bow, of things in heaven, and things in earth, and things under the earth;
And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.'
It's mighty strange that Baha'u'llah should suddenly claim the position of Christ when scripture clearly designates Jesus as the one and only Christ.
Of course, you may believe, as some do, that Jesus was totally misguided when he made the claim that the Hebrew scriptures all pointed to him as the Messiah.
Luke 24:25-27. 'Then he said unto them, O fools, and slow of heart to believe all that the prophets have spoken:
Ought not Christ to have suffered these things, and to enter into his glory?
And beginning at Moses and all the prophets, he expounded unto them in all the scripture the things concerning himself.'
