Do We Have Immortal Souls

To properly understand the immortality, or otherwise, of the human soul requires researching the scriptures with an open mind. A mind that is ready to accept what God reveals in His most amazing book.
The answer I have arrived at will be controversial and most people who belong to a tradition church will have been taught a very different understanding of our immortality.
The common belief is, when the good people die, they go to Heaven, but when those who have done wrong die, they will live for all eternity in Hell. A place where they will be eternally tormented for their sins against God. My question here is, just what sins warrant this type of punishment? Is there any sins so bad for God to punish those who commit them with this type of abuse and torture? Not for just a short period of time, but for all eternity.
The God I know is loving and compassionate. I do not believe He is that cruel and uncaring.
That said, I believe in a place called Hell, and it is certainly a place reserved for Satan. As for those who refuse to accept Jesus Christ as their Lord of Lords and King of Kings their future is in the lake of fire as is clearly described for us in
Rev 20:15 If anyone was not found written in the book of life, he was cast into the lake of fire.
This may sound like they have been cast into eternal damnation, but now let us consider
Mal 4:3 “You shall tread down the wicked; for they will be ashes under the soles of your feet in the day that I make,” says Yahweh of Armies.
They will be ashes, annihilated in the fire, nothing left but ashes. This is the fate of the wicked who refuse to repent of their sins and turn to God.
Not eternal punishing, but eternal punishment. There is a major difference between these two ideas. The first is non-stop punishing, while the second is to be punished once and for all. It will be eternal, because once they have become ashes, there will no longer be any part of them surviving either in Heaven or Hell. This is the punishment of a loving, just, and kind God.
