Jesus believed in Hell:
“But I say to you that everyone who is angry with his brother shall be guilty before the court; and whoever says to his brother, ‘You good-for-nothing,’ shall be guilty before the supreme court; and whoever says, ‘You fool,’ shall be guilty enough to go into the fiery hell.”
Hinnom was a deep, narrow ravine on the south side of Jerusalem. It is first mentioned in Joshua 15:8 (Cf. Jer.19:4-9). It had been the place where the idolatrous Jews burned their children alive to Moloch and Baal. A particular part of the valley was called Tophet, or the “fire-stove,” where children were burned. After the Exile, in order to show their abhorrence of the locality, the Jews made this valley the receptacle of the offal of the city, for the destruction of which a fire was, as is supposed, kept constantly burning there. The Jews associated with this valley these two ideas:
1.) That of the sufferings of the victims that had there been sacrificed; and
2.) That of filth and corruption. It became thus to the popular mind a symbol of the abode of the wicked hereafter. It came to signify “hell” as the place of the wicked.
The word Gehenna was never used in the time of Christ in any other sense than to denote the place of future punishment. “Hell” is a place of eternal punishment. It will be the future place of punishment for all who refuse to obey God. In this sense the word is used eleven times in our Lord’s discourses.
43* “If your hand causes you to stumble, cut it off; it is better for you to enter life crippled, than, having your two hands, to go into hell, into the unquenchable fire, 44* where THEIR WORM DOES NOT DIE, AND THE FIRE IS NOT QUENCHED.”
“Do not fear those who kill the body but are unable to kill the soul; but rather fear Him who is able to destroy both soul and body in hell.”
41 “The Son of Man will send forth His angels, and they will gather out of His kingdom all stumbling blocks, and those who commit lawlessness, 42 and will throw them into the furnace of fire; in that place there will be weeping and gnashing of teeth.”
33* “You serpents, you brood of vipers, how will you escape the sentence of hell?
And the devil who deceived them was thrown into the lake of fire and brimstone, where the beast and the false prophet are also; and they will be tormented day and night forever and ever.”
41* “Then He will also say to those on His left, ‘Depart from Me, accursed ones, into the eternal fire which has been prepared for the devil and his angels”
The good-news is you don’t have to go there!
