[Revelation 20:14] describes the end of the Judgement Age when all death and the concept of burial are thrown into the Lake of Fire to never afflict mankind again.
1 Corinthians 15
25 For he must reign until he has put all his enemies under his feet. 26 The last enemy to be destroyed is death. 27 For he “has put everything under his feet.” Now when it says that “everything” has been put under him, it is clear that this does not include God himself, who put everything under Christ. 28 When he has done this, then the Son himself will be made subject to him who put everything under him, so that God may be all in all.
