This is a discussion of DEATH - NOT of who will die or why or when or for how long, but the end of death, itself.
Our use of the first "death" in this title is to mean ruin, destruction or extinction (#5 below). The 2nd use of "death" in the title is the definition referred to when a person is dead (in death - #1a below). Said a different way, our title is "The Destruction of Death".

The Bible is very plain in saying that DEATH will end or be destroyed:
I will ransom them from the power of the grave; I will redeem them from death: O death, I will be thy plagues; O grave, I will be thy destruction: repentance [regret] shall be hid from mine eyes. Hosea 13:14
This verse is spoken directly to the children of Yahweh ("them"), the Israelites. These promises will apply to all His children, as shown in the following verse. Even though spoken specifically to "them", Yahweh will be the destruction of the grave (generally, NOT just Israeli graves).
And he will destroy in this mountain the face of the covering cast over all people, and the vail that is spread over all nations. He will swallow up death in victory; and the Lord God will wipe away tears from off all faces; and the rebuke of his people shall he take away from off all the earth: for the Lord hath spoken it. Isaiah 25:7-8
Isaiah's promise is to "all people" and "all nations" (Isaiah 25:7). Death itself (all death) will be swallowed up. Tears will be wiped away from "all eyes".
The last enemy that shall be destroyed is death. 1 Corinthians 15:26
Death is an enemy of all. Death will be destroyed. Not just "a little" death. Not "some" death". Not "dying". Death will be destroyed.
So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory. O death, where is thy sting? O grave, where is thy victory? 1 Corinthians 15:54-55
This is quoting from Isaiah 25:8.
But is now made manifest by the appearing of our Saviour Jesus Christ, who hath abolished death, and hath brought life and immortality to light through the gospel: 2 Timothy 1:10
And the sea gave up the dead which were in it; and death and hell delivered up the dead which were in them: and they were judged every man according to their works. And death and hell were cast into the lake of fire. Revelation 20:13-14
All the dead (remember, these are those who did NOT "go to Heaven") will be "delivered up" for judgment. Then death and hell will be destroyed by casting them (death and hell) in the fire.
And God shall wipe away ALL tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away. Revelation 21:4
Notice that it is DEATH that is destroyed, not DYING.
What is the difference? If "dying" were destroyed, it means that there would be no NEW deaths (no more dying) but that says nothing about previous deaths (those who previously died, the ALREADY dead). They would still be dead and death would NOT have been destroyed.
The end of dying is not the same as the end of death.
The destruction of dying is not the destruction of death.
Wiping "away tears from off all faces" is not accomplished through hypnosis or erased memories or the passing of time or rationalizing that death was deserved or for a good purpose or to serve justice or because it was their (free)will choice. There is only one thing that will dry tears - resurrection and salvation (restoration) and return of the lost loved one.
Only then will death be destroyed and tears dried.
As long as there are still dead people in graves, death has not been destroyed, tears have not been dried.
As long as anyone mourns the loss of a loved one, their tears are not dried and death has not been destroyed, abolished, swallowed up, existing no more.
The only thing that will end death is when there are no dead. We are promised this - the destruction of death. The death of death. The resurrection and restoration of ALL the dead, so none remain dead - none remain in death.
THEN, death will have been destroyed.
