Baha’u’llah is in no way Biblical and doesn’t fit to the Biblical announcement. So, could you tell why should anyone receive Baha’u’llah? Why have you received him and why lift him to same category with Jesus?
When Jesus first appeared the Pharisees said the same thing that He did not fulfil their prophecies in the Torah regarding the Messiah.So scriptures can be used to both reject and accept. What made the disciples accept Jesus? It was the Person, life and teachings of Jesus and their purity of heart that led them to believe in Him.
And this was handed down through the Bible and the pure hearted accepted Him as purity of heart is the quality necessary to ‘see God’ as He said ‘ Blessed are the pure in heart for they shall see God’. So even though people of today never met Jesus, their purity of heart can confirm for them that He was indeed the Messiah with the Gospels a further confirmation.
The same with Baha’u’llah. His Life and Person and teachings that have been passed down have enabled the pure in heart to recognise that He was Christ returned in the glory of the Father. Just like your heart can not deny that Jesus is true so too my heart can not deny the truth of Baha’u’llah. Non Christians will say you are wrong but you know in your heart that Jesus was true. Likewise non Baha’is can say Baha’u’llah is not true but I know in my heart He is.
Just as Christ came in the station of the Son, Baha’u’llah came in the station of the Father and brought the Kingdom of God with Him as promised in the Lord’s Prayer.
So we both believe in Jesus, the difference between us being that you have only accepted His first coming while I accept both His first coming and also when He returned in the glory of the Father - Baha’u’llah.
Of course like the Jews rejected Christ citing their scriptures you too also are free to reject Baha’u’llah citing your scriptures. That didn’t make them right and also doesn't make you right
But the Jews rejection of Christ didn’t stop humanity from accepting Jesus just as rejection of Baha’u’llah won’t stop the world from accepting Him.
All that happened was that the Jews got left behind. So too those who reject Baha’u’llah will just get left behind because God endowed man with free will to accept or reject Him.
Im glad I searched deeply into Who Baha’u’llah is because that has given me the bounty of being among the early ones who have accepted Christ’s second coming. If I only accepted His first coming and rejected Him when He returned then I would have shown myself to have been unfaithful to Him and as I really love Jesus with all my heart I cannot betray Him and not to accept Baha’u’llah to me personally would be unfaithfulness to Jesus as I believe He foretold Baha’u’llah.
