OK, from what I have seen so far on this thread, is that it's pretty much split between those who say they will burn in the lake of fire, and those that say the Lord will forgive them. Let me give you an incident of suicide that ought to trigger your thoughts, and let me know if you still stand behind your decisions.
"I'm leading my squad of Marines on patrol one day. Our point man, PFC Knucklehead, spots a platoon of the enemy ahead. We splilt up and set up an ambush for them. Once they are in range, we open fire on them. Next to me are my radio man, navigation man, and the corpsmen. All of a sudden, a grenade rolls into our area. The Navigator jumps on the grenade, thereby committing suicide in the act, but saves 3 other people from death. Will God send him to Hell for such a "damning" act, even this was suicide, and he made the decision to kill himself?"
No, I do not believe the Lord will send someone to Hell, simply because they committed suicide. Not one verse in the Bible says that one sin after repentence will be unforgiveable, nor is it any indication of that. So, if you are having sex outside of marriage and you have a heart attack and die, do you go to hell, simply because you were engaged in a sinful act, one of which is to bring self pleasure and is not in keeping with the Law of the 10 Commandments? Just a little food for thought.
