I believe with all my heart that Heavenly Father is a loving and forgiving God! As a mother I know how much I love my children and that I want to give them every opportunity for happiness and success. I can only imagine how much more my Heavenly Father wants those things for His children. However He has given each of us free agency to choose how we will live this life. Part of that choice is eternal salvation or eternal damnation. First of all, I believe it would be extremely difficult to get to the point of sin where you would be thrown into outer darkness, but I know that this world has seen extremely dark and evil men and women. I believe that when we are at the final judgment and we have a perfect memory of all of our sins that we did not repent of, I can only imagine how unworthy I myself would feel to be in the presence of my God and my Savior. So, I think this is where eternal damnation comes into play, for those that are so unworthy they would not feel comfortable in His presence. Just as in life they were comfortable living in such sin and ungodliness it will be the same for them in eternity and I think for them to never be able to be in His presence and to be with Lucifer who hates us and wants us to be miserable, that is their damnation.
Where does the Bible say Lucifer (Satan) is death proof? Isn't Satan a sinner? A sinner pays the price of sin which is death. According to Hebrews (2:14 B) isn't Satan destroyed?
Since emptied-out hell experiences second death (Rev 20:13,14) and those delivered up from hell are not in hell who would Satan be with if he was there?
Yes, our Heavenly Father is a loving and forgiving God and that would mean he has to be a just God and care for the righteous ones in order for justice to be carried out. Isn't that why Jesus cautioned about the unforgivable sin of Matthew 12:32? What does Hebrews (6:4-6) say? or Hebrews (10:26)?
What is the damnation of Gehenna (hellfire)? Gehenna was a place of destruction. It was not a place where things were kept burning forever.
Gehenna thus is a fitting symbol of destruction.
