Baha'u'llah wrote according to what He heard from God, He did not need to refer to the Bible.
“O KING! I was but a man like others, asleep upon My couch, when lo, the breezes of the All-Glorious were wafted over Me, and taught Me the knowledge of all that hath been. This thing is not from Me, but from One Who is Almighty and All-Knowing. And He bade Me lift up My voice between earth and heaven, and for this there befell Me what hath caused the tears of every man of understanding to flow.” Proclamation of Bahá’u’lláh, p. 57
I consider what you believe to be a fantasy which is based upon misinterpretation of the Bible.
There will be a Kingdom of God that comes to earth. When the Kingdom of God comes to earth there will be no more poverty, no lack of food and no more war, but that is not the same as the joy and gladness we will experience in heaven. There will always be sickness and death on earth; although as medical science advances there will be less disease, people will continue to die at the end of their life spans.
Nobody who has died will ever live again in a physical body on earth; everyone who dies will live again in a spiritual body in the spiritual world.
Paul was very clear on what will happen when we die. Our physical bodies will be transformed into bodies that will never die. Our transformed bodies will be spiritual bodies. Paul says that our physical bodies cannot inherit the Kingdom of God and that means they cannot exist in heaven. When Paul said these dying bodies cannot inherit what will last forever, Paul was referring to the spiritual world (heaven), which will last forever.
1 Corinthians 15:40-54 New Living Translation
40 There are also bodies in the heavens and bodies on the earth. The glory of the heavenly bodies is different from the glory of the earthly bodies.
44 They are buried as natural human bodies, but they will be raised as spiritual bodies. For just as there are natural bodies, there are also spiritual bodies.
50 What I am saying, dear brothers and sisters, is that our physical bodies cannot inherit the Kingdom of God. These dying bodies cannot inherit what will last forever.
51 But let me reveal to you a wonderful secret. We will not all die, but we will all be transformed!
54 Then, when our dying bodies have been transformed into bodies that will never die,[c] this Scripture will be fulfilled: “Death is swallowed up in victory.[d]
