In Islam people do receive punishment, but everyone receives paradise eventually and that will last forever, and this is according to the same God of the Bible.... now you might be thinking "how can a God change his mind like that?, Since in the Bible it talks about being in hell forever if you don't accept Christ as your savior"... well the only reason for the difference is because man altered God's word and his teachings after Christ died, so by the time they wrote the New Testament 65-100 years after Christ the word had been altered and changed.
So yes, God will send people to hell fire. Yes, it sounds cruel, but God gave a clear warning to everyone and he also gave everyone a guidline to follow which would keep you away from this. What more could you want? He's given you the answers to the test, who fails a test when they have all the answers? Would you rather God not warn you about hell? If God didn't warn the people of such a thing, come the day of Judgment when God sends people to hell, their reaction would be "Well if I knew there was a hell and you made it clear to me, I wouldn't have done all this sinning" but clearly that's not the case because now people hold a grudge against God for stating that if you do wrong, and you sin, and you do evil, you will receive hell fire. It's a lose/lose situation.
God will bestow his mercy upon whoever he pleases. The only person God says he wont bestow his mercy on is a liar, a person who lives a life of lies and lies to everyone around them, other than that you have a chance at Gods mercy. A non-believer can receive Gods mercy and I'll bet the bank that many of them will. For those who don't receive God's mercy from hell, they will eventually receive His mercy anyway... becasue like I stated above God will grant them paradise after their punishment is done. Again, I am repeating myself but it is almost as if hell is a cleansing of the soul or spirit, and a replenishment. Maybe a spirit or soul who has sinned and gone so far off the path needs to receive the fire to be able to enter paradise. Maybe the hellfire God speaks of isn't actually a firey pit, but the body feels an unbelievable amount of grief/regret/lonliness when God is no longer with them and it feels like a burning in the body. Who knows what hell is, but I know it's somewhere that I don't want to go. I believe in being good, and if you follow God and His way, then you are being good. I believe in staying healthy, and if you believe in God and his way, you will be healthy.Now some people don't need God to be good to others, and to keep their body healthy, but I think the ones who do it so naturally are being guided by God without even knowing it.
I've stated this a thousand times before on these threads, but the fact that we all come to this site everyday or every other day to gain knowledge and speak about life, and try to find out the answers to what is going on in the world today is a good deed. God loves that we do this, God loves those who gain knowledge and seek to find the truth. Although you may not be a believer in God, you are still learning, and reading and educating yourself, and as long as you dont stop learning and searching for the answers I believe God will bestow his Mercy upon you. I believe this because if there is a God, then He is the answer. If you were searching and gaining knowledge and learning about all different kinds of faiths, and learning about science and the history of the world, and trying to find out why we're here, then you were searching for God your whole life without even knowing it, and he will reward you for that.
A good deed is a good deed whether you believe in God or not. No good deed will go un-noticed, but the same goes for the bad. The state of the human beings heart will have a huge bearing on Gods mercy. How the human being reacts to finding out that there is a God after not believing there whole life will mean a lot. God knows what is in the heart of the human being, and God knows what we really believe and think. If the person who didnt believe their whole life finds out the truth and is still against it, and still speaks against God, that person will probobly receive hellfire. Now I can't say that they will, because I don't know how God will do his judging, but I believe that person will deserve it, due to such ignorance and lack of respect. Now I was speaking as if there was gonna be a Judgment Day for sure, but I want everyone to know that this is through my eyes and my perspective... and for those who don't believe in a day of Judgment just take it for what it's worth... I dont want to offend anyone, and if I did , I apologize.
