No, that's not true, UR actually changes the meanings of even the original words like -death.
UR doesn't believe the second death really means death.
Greek word 2288 thanatos, death, deadly, death. If death doesn't really mean death, what else can be changed?
There are other words to describe redemptive measures and that's not one of them. And to use verses when God tries somebody in their lifetime symbolic of refining them through fire is not the same thing as the Lake of Fire prepared for Satan and his. To even claim it's the same thing is totally off the mark. Again our Father tests and tries his elect through their lifetime, not after Judgement day.
For example -
Zechariah 13:8 "And it shall come to pass, that in all the land, saith the Lord, two parts therein shall be cut off and die; but the third shall be left therein."
Zechariah 13:9 "And I will bring a third part through the fire, and will refine them as silver is refined, and will try them as gold is tried: they shall call on my name, and I will hear them: I will say, It is my people: and they shall say, The Lord is my God."
Anyone can pull verses out of context to prove anything. The above verse was quoted to me from someone on this board promoting UR- but of course left out verse 13:8.
We have to keep things in context.
So if taking the word death back to the Greek? What is your definition?
