Hi Casi,
As long as this thread is I figured you must have already gotten a response from a Baha'i, but I just looked through and didn't see one.
From a Baha'i perspective, heaven and hell are not physical places, but rather states of being. Heaven being nearness to God, and Hell being remoteness from God. Including infinite states between the two extremes.
The purpose in holding this belief to me, is that it puts the responsibility of our spiritual destination solely on our own shoulders. Our job in this life is to develop our spiritual life, striving to cultivate our lives in line with spiritual principles. There is no automatic admittance, words without deeds are of little value. Also, the purpose in holding this belief is the understanding that no one group of people has a corner on the market of heaven. Each and every person is responsible for one life only and that is their own.
In the Baha'i belief, we can only make spiritual progress of our own accord while on earth, once we die, our progress lies with the mercy of God, and in the prayers offered on our behalf. But we do not believe that hell is eternal. We believe all souls will continue to make progress until they attain the presence of God.
