Christians: what's your view on Revelations 21:8?

It is avoided by believing in the Lord Jesus Christ.  Here is the truth: The Lord Jesus Christ is God. Nobody can be good enough to avoid hell. The truth is that death leads to immediate heaven or hell, depending only on whether the person believed on the Lord Jesus Christ, or not. The truth is that the Lord Jesus Christ loves you and wants to bless your life freely :) Most of all, Jesus wants you with Him forever, and not in hell.
.
Believing on the Lord Jesus Christ means being forgiven all sins past and future and means going to heaven. The truth is that every belief except one will lead to eternal torment in the lake of fire for every person. Because nothing pays for our sins except the death and blood of Jesus, the sacrifice of Jesus that is already accomplished by Him . Jesus loves you! The truth is that the Lord Jesus Christ is God, and Jesus died on the cross to pay for all of our sins in full, and then Jesus was buried, and then Jesus resurrected from the dead. Nothing else pays for our sins, not works, not deeds, not religions. So the only way to heaven and to avoid hell, is by believing on Jesus for eternal life (John 6:47), without adding any of your own works (Romans 4:5). Believe in the Lord Jesus Christ to take you to heaven, and you will be in heaven, no matter what, guaranteed. That easy, thanks to Jesus! Tell Jesus that you thank Him that you will be with Him in heaven

 A judgment of eternal destruction has been determined for Satan, his demons, the symbolic “wild beast” and “false prophet,” and even death and Hades. (Mt 25:41; Re 20:10, 14, 15; 21:8)
Permanent destruction also awaits those who by choice “do not know God and those who do not obey the good news.” (2Th 1:8, 9)
Fire was used in Bible times as the most thorough means of destruction. Hence, Jesus used fire to illustrate the complete destruction of the wicked.—Mt 13:40-42, 49, 50

All those who reject YHVH GOD and Yeshua Messiah automatically choose the Lake of Fire.

You know nothing about that verse, troll

Lake of fire: a 
symbolic place that “burns with fire and sulfur,” also described as “the second death.” Unrepentant sinners, the Devil, and even death and the Grave (or, Hades) are thrown into it. The inclusion of a spirit creature and also of death and Hades, all of which cannot be affected by fire, indicates that this lake is a symbol, not of everlasting torment, but of everlasting destruction.​—Re 19:20; 20:14, 15; 21:8.

My view is that like all scripture, it is true.  And it provides a powerful reason for me to share with others about Jesus Christ that they might escape the judgment to come.

Superstitious nonsense misinterpreted from writings that were describing events current to the writer(s).

The entire book of 'revelations' is written in a kind of 'code' to prevent the people who they were talking about from knowing what was being said about them.
