I also do not believe in an eternally burning hell, as the world teaches it. You started this thread quoting (I believe yourself) that the KJV has hell mistranslated. The words are correct in the KJV. Man's interpretation upon it is incorrect. Some take the strong language used in the verses (for example, found in Revelation) to be very literal. When you encounter such an error, present the truth surrounding those verses.
Revelation 20:7-10 And when the thousand years are expired, Satan shall be loosed out of his prison, and shall go out to deceive the nations which are in the four quarters of the earth, Gog and Magog, to gather them together to battle: the number of whom is as the sand of the sea. And 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. And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever.
Revelation 14:9-12 And the third angel followed them, saying with a loud voice, If any man worship the beast and his image, and receive his mark in his forehead, or in his hand, the same shall drink of the wine of the wrath of God, which is poured out without mixture into the cup of his indignation; and he shall be tormented with fire and brimstone in the presence of the holy angels, and in the presence of the Lamb: and the smoke of their torment ascendeth up for ever and ever: and they have no rest day nor night, who worship the beast and his image, and whosoever receiveth the mark of his name. Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus.
It would be good to present to people that the lake of fire and brimstone surrounds the camp of the saints, and is supposed to burn for ever and ever (not for eternity, but for a long time). Show people that if they believe this is for all eternity, then the wicked shall be burning for all eternity in the presence of the saints, the angels, and in Jesus. Being in the presence of Jesus would also contradict the meaning of what some people believe, that they would have an eternity without God's presence. The scriptures clearly paint the picture of them being in Jesus's presence when the wicked are burning.
Now, as someone who does not believe in hell the way the world does, let me post this:
Malachi 4:1-3 For, behold, the day cometh, that shall burn as an oven; and all the proud, yea, and all that do wickedly, shall be stubble: and the day that cometh shall burn them up, saith the Lord of hosts, that it shall leave them neither root nor branch. But unto you that fear my name shall the Sun of righteousness arise with healing in his wings; and ye shall go forth, and grow up as calves of the stall. And ye shall tread down the wicked; for they shall be ashes under the soles of your feet in the day that I shall do this, saith the Lord of hosts.
There cannot be universal salvation. Notice that those that are burned shall be as stubble. Isaiah 5:24 talks about how the wicked shall be devoured by fire as well, the same way the fire devours the stubble, and flame consumes the chaff. Devour in this sense with fire refers to destroying and/or consuming. And consume here means to totally destroy. The wicked shall be totally destroyed. And verse 3 makes it plain, that the righteous shall be walking on the ashes of the wicked, and that there shall be neither root nor branch.
Universal reconciliation is not true. (See also Isaiah 5:20-25, Nahum 1:9-10, Ezekiel 28:18-19 (which talks about Satan)). There are more verses of course. For example, simple verses such as Romans 6:23. The wages of sin is not eternal life, but death. Therefore, how can the wicked live eternally, after choosing a life of sin? They shall die, not live for all eternity.
