Someone in hell is spiritually dead and cannot pray.
Well the possibility JP11 is in hell and cannot pray is just that - a possibility.
If you were dead, and by chance in Heaven, you would not be concerned at all about your loved ones you left behind on Earth?
You would have no feelings at all for them?
You would have completely forgotten about them?
If God is concerned about us on Earth, and he is in Heaven, what makes us all high and mighty that we would have no concern at all for people on Earth, when God is concerned about us on Earth?
"...Thy will be done on Earth as it is in Heaven."
No, Bipolar, we were made to be concerned about all souls everywhere, anywhere they are, whether they are dead or alive.
In the Bible, the Jews prayed that their dead loved ones would be loosed from their sins. The Jews of the Old Testament prayed for their loved ones out of concern for their souls.
We should do no less.
