I don't believe in an eternal firey place where people who did not accept Christ are tortured for the rest of enternity. That's just not in the Bible. It's another doctrine of man, and is one of Satan's tools to lead people away from the truth.
If you know anything about God's character you will know that He is a loving and Just God. He is a God of love, not a God of force. God gave us free will to decide. Take that into account next time you try to scare someone into Christianity with Hell. This has done more work to turn people away from the truth than many realize.
So do bad people go to hell when they die? This is commonly what people are taught. But what does the Bible say?
"The Lord knoweth how to deliver the godly out of temptations, and to reserve the unjust unto the day of judgment to be punished." 2 Peter 2:9.
"So shall it be in the end of this world. The Son of man shall send forth his angels, and they shall gather out of his kingdom all things that offend, and them which do iniquity; And shall cast them into a furnace of fire." Matthew 13:40-42.
"The word that I have spoken, the same shall judge him in the last day." John 12:48.
It says that God will reserve the unjust's punishment until the day of judgement. When is the day of Judgement? It's one of the very last events, at the very end of the world.
HOWEVER...
"The wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord." Romans 6:23.
"Sin, when it is finished, bringeth forth death." James 1:15.
"God so loved the world that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life." John 3:16.
The wages of sin are death... not eternal hellfire.
"But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death." Revelation 21:8.
The wicked die the second death in hellfire. If the wicked lived forever being tortured in hell, they would be immortal. But this is impossible, because the Bible says God "only hath immortality." 1 Timothy 6:16.
The Bible says the wicked suffer "death" (Romans 6:23), will suffer "destruction" (Job 21:30), "shall perish" (Psalm 37:20), will "burn" up (Malachi 4:1), "shall be destroyed together" (Psalm 37:38), will "consume away" (Psalm 37:20), "shall be cut off" (Psalm 37:9), "shall be slain" (Psalm 62:3). God will "destroy" them (Psalm 145:20), and "fire shall devour them" (Psalm 21:9). Note that all of these references make it clear that the wicked die and are destroyed. They do not live forever in misery.
"So shall it be in the end of this world. The Son of man ... shall cast them into a furnace of fire." Matthew 13:40-42.
"They went up on the breadth of the earth, and compassed the camp of the saints about, and the beloved city: and fire came down from God out of heaven, and devoured them." Revelation 20:9.
"The righteous shall be recompensed in the earth: much more the wicked and the sinner." Proverbs 11:31.
"The day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up." 2 Peter 3:10.
It happens at the end of time when the wicked try to capture the New Jerusalem, but God sends hellfire down on them. It's so hot that it burns up all the works on this earth and melts the elements. The heavens pass away with great noise too.
What does the Bible say about how long the wicked will be punished in Hellfire?
"And, behold, I come quickly; and my reward is with me, to give every man according as his work shall be." Revelation 22:12.
"And then he shall reward every man according to his works." Matthew 16:27.
"That servant, which knew his lord's will, and ... neither did according to his will, shall be beaten with many stripes. But he that knew not, and did commit things worthy of stripes, shall be beaten with few stripes." Luke 12:47, 48.
The Bible doesn't tell how long the wicked will be punished before receiving death in the fire. It does say though, that all will be punished according to their deeds. This means some will receive greater punishment than others, based upon their works
"As I live, saith the Lord God, I have no pleasure in the death of the wicked; but that the wicked turn from his way and live: turn ye, turn ye from your evil ways; for why will ye die?" Ezekiel 33:11.
"For the Son of man is not come to destroy men's lives, but to save them." Luke 9:56.
"For the Lord shall rise up ... that he may do his work, his strange work; and bring to pass his act, his strange act." Isaiah 28:21.
Destroying sinners is completely against God's nature. However, in order to eradicate sin forever, there has to be something done about it. One sinner left alive would be like a virus, so in order to end all of that and bring about a new Heaven and new Earth where everything we know of from this world is gone forever... God brings about distruction. It's a strange act for Him. If God were to destroy these people for eternity it would make God out to be a horrible tyrant. Who would want to joyfully and lovingly follow a tyrant?
