We should desire to experience the lake of fire if God sees that is what we need. That's how much we can relax in the arms of God's love.

It is God’s decretive will (that which MUST occur) that everyone violates His preceptive will (that which they OUGHT to do) as much as they actually do because each person is being fitted into God’s master plan in a way that necessitates their own individual experience with sin, evil and suffering.

The process of salvation will be completed for the firstfruits of election, (the remnant chosen by grace), after the first resurrection. The process of salvation will be completed for the non-elect after the great white throne judgment. For some, it will include an experience in the lake of fire.
But everyone will be saved out of the lake of fire which is the second death.

You may ask, “What scriptural evidence is there of being saved out of the lake of fire which is the second death?"

There actually is much evidence.

Although the book of Revelation is the last book placed in the Bible, it is not the final revelation of what God is going to do with humanity. The apostle Paul saw way beyond John.

Col.1:25 of which I became a dispenser, in accord with the administration of God, which is granted to me for you, to complete the word of God

There is much evidence that Paul did see way beyond John. For instance, in Revelation there are still kings reigning, and Christ is still reigning along with His followers. There are still sovereignties and powers in force throughout the book of revelation. So John did not see the day when all sovereignty, authority and power would be done away. Paul did. If you will look at 1Corinthians 15:24-28 Paul saw the day when all of these would be done away. He sees the day when "He should be nullifying all sovereignty, authority and power" (vs.24)

Paul sees the day when Christ will quit reigning (vs.25).

Paul sees the day when death (all death which includes the second death) will be abolished (vs.26). Please remember that death will be abolished **after** all the sovereignties, authorities and powers in Revelation have been nullified. Within the book of Revelation, death is still operational as are the afore mentioned powers.

So what is going to happen to all these people who are in death when death is abolished?

They will come forth vivified (made alive beyond the reach of death) (1Cor.15:22).

They will have their lives justified and will be constituted righteous:

Romans 5:18 Consequently, then, as it was through one offense for all mankind for condemnation, thus also it is through one just award for all mankind for life's justifying.
Romans 5:19 For even as, through the disobedience of the one man, the many were constituted sinners, thus also, through the obedience of the One, the many shall be constituted just.

All will be reconciled to God (Col.1:20)

All will be headed up in Christ (Eph.1:10)

All will bow the knee in the name of Jesus and acclaim with their tongue that "Jesus Christ is Lord" to the glory of God, the Father (Phil.2:9-11).
And we know that anyone who acclaims that Jesus Christ is Lord, especially when it is to God's glory without any hypocrisy is saved for 1Corinthians 12:3 says so.

So there is proof that people will go to the second death **when ** the new earth comes. And there is proof that this is not the final goal God has for these people.

In summary then:
The lake of fire is the second death.
The apostle John did not see into the future as far as the apostle Paul.
How do I know this? and what ramifications does this have as to whether or not one gets out of the lake of fire...the second death? Plenty.
In the book of revelation Christ is still reigning; death is still operational; sovereignties, authorities and powers are still in force.
In 1Cor.15:22-28 Paul sees way beyond John's revelation.
He sees the day when Christ will quit reigning (1Cor.15:25).
He sees the day when all sovereignties, authorities and powers are nullified (1Cor.15:24).
He sees the day when death is abolished (1Cor.15:26) and all are then subjected to Christ then Christ is subjected to God and then God is All in all (1Cor.15:28).
So, yes, there is scripture which intimates that all in the lake of fire will come forth and God will be All in all.
Also in 1Cor.15:22 all are dying and in Christ shall all be vivified. So this happens after death for most.
Also in Romans 5:18,19 you have what happens to all mankind due to what Adam did which happens to the exact same all mankind due to what Christ did. But it does not happen to all at the exact same time.
