So when it doesn't fit your claim of 'no Hell in the old testament', it just becomes rhetoric?
It (your quote) doesn't describe a Christian version of hell.
Second, did you bother to read the whole chapter?
Daniel 12:4 said:
4 But you, Daniel, keep the words secret and the book sealed until the time of the end. Many shall be running back and forth, and evil shall increase.”
9 He said, “Go your way, Daniel, for the words are to remain secret and sealed until the time of the end.
It state that "Daniel" should keep the book hidden until it was time to reveal it. That Daniel himself must reveal it.
Now, if this secret was Daniel's secret to reveal, and if this secret was supposed to be reveal during Jesus' ministry, then where is Daniel?
"...keep the words secret and the book sealed until the time of the end."
What you have quoted, the 1st two verses would be all good, but verse 4 is also relevant to the earlier verses, except that Daniel never appear in the gospels or the Revelation to reveal anything.
Twice, the one speaking to Daniel commanded that he must keep it a secret until it is time or more precisely "the time of the end". The whole chapter could mean anything, but it would seem that secret has to be reveal during Daniel's lifetime.
Daniel was to keep the secret, and Daniel was meant to reveal that secret -
"until the time of the end".
So when is "the time of end"? When will Daniel know "the time of the end", for Daniel himself to reveal it? How will Daniel know it is time? Will Daniel be around to reveal the secret?
I hate Christians who quote a verse or two, twist the meaning for their own agenda, expect us to accept their interpretations without question, WITHOUT BOTHERING TO READ THE WHOLE CHAPTER.
You are cherry-picking the verse.
Where is the "lake of fire" and "brimstone" in Daniel 12:1-2 or any part of Daniel 12?
This "lake of fire" and "brimstone" is mention 3 times in Revelation - 19:20, 20:10 and 21:8 - of what will happen to the beast and the false prophet (19:20), to the devil (and the beast and false prophet mentioned again in 20:10), and lastly, to all the sinners (last verse, 21:8).
Daniel 12, only state "...and some to shame and everlasting contempt." This is rather vague, and doesn't anywhere describe hell as the "lake of fire".
Daniel state that Michael is the protector of "your people", and he shall arise to protect them. I am assuming that the "people" is referring to that of Judah. Sorry, but where is Michael, the protector, in the gospels?
I only see Michael in Revelation, when he fight the "dragon" aka the Devil aka Satan, but not in the gospels. So how Michael relevant in all this. So unless you think Jesus is Michael, the chapter, not just the verses that you have cited, is far too metaphoric and obscure, to be taken literal, and it doesn't match up with the hell in the New Testament.
