This may be a very funny statement PR, but the reality is that heaven is a place where QUALITIES are experienced.
If your experience of heaven is one of joy, then I would posit that there may well be someone who is experiencing MORE joy, since joy is an attribute of the soul.
The reason why Baha’is believe that this is an infinite journey for the soul, is that the soul is the body of the entire attributes of God. As these attributes are developed and the soul manifests more and more the attributes of God, naturally, this would imply that we would become more and more ONE with God, and “experience” more and more FULLY this “beautific vision”, which really is not a totally foreign concept to Baha’is (although it is a term not used)
Since qualities and attributes are infinite and they can be infinitely developed (i.e… however much you are loving, there is always a possibility to be more loving. However much you are just, there is always a possibility to be more just) it is naturally realistic to imply that your soul, which harbours these attributes of God, progresses and perfects itself infinitely.
It may sound daunting to human minds that consider journeys according to “human” and “physical” terms, and relate a journey to “time” however, we must remember that the spiritual world that the Baha’i theology is putting forward is devoid of ALL physical things, and as a result, there is no sun, and therefore there is no time.
Having no time is a concept beyond human comprehension, so how it “looks” in the next world is as unknown as the “new heaven and new earth” that Christianity posits (and I personally believe that they are the same thing).
Don’t worry however, when we are spiritually developing our soul according to the Will of God, then the bliss will be beyond anything experienced on this earthly plane, and will continue to get more blissful eternally. Just when you thought “Wow!! This is so blissful, being in the presence of God!!” …suddenly you are propelled towards an EVEN MORE blissful state of greater and closer communion with your Beloved.
I pray and hope these thoughts will be worthy of your consideration
