Jesus is speaking about the heavenly resurrection here...that is called the 'first' resurrection and it is specifically for those who will be joint heirs with Christ in the kingdom of God. These ones are given immortality.
I think it says 'they are like angels' with reference to their gender... not with reference to living or dieing. The context of the verses surrounding it is about marrying and remarrying. The angels are without gender and therefore do not marry and this is going to be the same for those who partake of the 'first' resurrection. In heaven they will not marry like the angels.
1. Jesus was addressing a question posed by the Sadducees, in order to trap Him, concerning the marriage of a woman
whose 7 husbands die without ever giving her children(vs 28-33). After addressing their question about the marriage portion (vs34-35), Jesus answered their real question about the resurrection (remember the Sadducees did not believe in a resurrection) to which He explained how in our immortal state, we will be equal to angels in that neither one of us will be able to marry or die (vs36).
“the lake of fire and sulphur” can not be a literal place.
2. I categorically disagree...This is the same fire and literal punishment spoken of in Rev 20:13-15.
2Pe 3:7 But by the same word the present heavens and earth are held in store for fire, being kept until the day of judgment and destruction of ungodly men.
2 Pet 3:10,12 "But the day of the Lord will come as a thief in the night, in which the heavens will pass away with a great noise, and the elements will melt with fervent heat; both the earth and the works that are in it will be burned up. 11 Therefore, since all these things will be dissolved, what manner of persons ought you to be in holy conduct and godliness, 12 looking for and hastening the coming of the day of God, because of which the heavens will be dissolved, being on fire, and the elements will melt with fervent heat?
Also notice the words of Jesus:
Luk 12:49 "I came to send fire on the earth, and how I wish it were already kindled!
Revelation 20:14 says that death itself, along with Hades, is thrown into it. Surely, death and Hades cannot suffer pain because they are not tangible things that exist. "And death and Ha′des were hurled into the lake of fire. This means the second death, the lake of fire. 15 Furthermore, whoever was not found written in the book of life was hurled into the lake of fire"
And this is why we read of the final outcome will be as Revelation 21:4, says: “He will wipe out every tear from their eyes, and death will be no more,neither will mourning nor outcry nor pain be any more.[/I] The former things have passed away. ”
3. The term Death and Hades is synonymous with death and the grave. Rev 20:13-15 speaks of a final resurrection (vs13), sometime after the millenium, of physical unrepentant humans (2 Pet 3:7) whose name was not found in the book of life (vs15). These humans will be cast in the lake fire, be burned up, and cease to exist.
Everyone else, at this point, would be composed of spirit. Death will no longer exist. The need for a grave will be a thing of the past and in essence destroyed in this worldwide inferno. Paul echoes Isaiah's sentiment (Isa 25:8) in 1 Cor 15:54-55 when he states, "....Death is swallowed up in victory 55 "O death, where is your sting? O hades, where is your victory." Satan and his demons will also be cast into this lake of fire and be tormented not destroyed. After all of the combustible material is burned up, the fire will die out but satan and his demons torment will continue by being confined to the abyss (bottomless pit) forever! Notice how much they fear this place!!
Luk 8:31 And they [demons] begged Him [Jesus] that He would not command them to go out into the abyss. NKJV
In the parallel account, Matthew records a key statement missing in Luke's account made by the same demon which irrefutably supports that demon spirits will be tormented in the abyss not destroyed in the lake of fire forever!
Mat 8:29 And suddenly they cried out, saying, "What have we to do with You, Jesus, You Son of God? Have You come here to torment us before the time?"
Notice he did not say "destroy us" before our time. Did you also notice the statement "before our time"-- what time? The time of their eternal torment with satan in Rev 20:10!!!!! .
Scriptures undeniably confirm that Satan and His demons will be cast into the worldwide lake of fire as a symbolic act of purging and destruction of the origins of sin, along with all physical ungodly men. Once all combustible material is burned up, their ultimate fate, as scriptures clearly indicate, will be torment in the abyss forever!! Not destruction in the lake of fire forever!!
So the lake of fire is symbolic of complete destruction. This means that Satan will be completely destroyed forever, eternally[
4. Unrepentant physical humans will be burned up (Mal 4:1-3); cease to exist and be destroyed forever. Fallen Spirits will not. They will be tormented--- Luke 20:35-36; Mat 25:41; Rev 20:10 says so!!
Satan and his demons were created as eternal beings with awesome power which they have grossly abused. They were given much so much was expected (Luk 12:48). Their sin requires stricter punishment. Simply destroying them forever would be no stricter punishment than that of unrepentant humans which were given much less.
After the earth is purged by fire, Satan and demons will no longer have any physical humans or animals to influence, torment, and possess. Their habitat will be purged and destroyed. They will be confined to the abyss forever which Scripture points out will absolutely horrify and mentally torment them for all eternity! This punishment most certainly fits the crime.
..Except for the unconcious statement. Unconscious is not technically considered dead. But I'll take it
