if you woke up tomorrow and everyone on the entire planet was immune to death(only from age, people can still die from murderer, accidents, suicide, etc), what do you think would happen and what are your thoughts on it as a religious person?
I find the coming of 'No more death ' on Earth is a biblical teaching as found at 1 Corinthians 15:26; Isaiah 25:8.
What I think will happen is: that there will be ' healing ' for earth's nations as mentioned at Revelation 22:2.
Mankind will see the return of the Genesis ' tree of life ' on Earth for the healing of earth's nations.
Through Jesus, then God will fulfill His promise to father Abraham that ALL families of Earth will be blessed - Genesis 12:3
And ALL nations of Earth will be blessed - Genesis 22:18. Blessed with the benefit of healing health for everyone.
No overpopulation, No food shortage because only upright or humble meek people will inherit the Earth.
As for wicked people they will be 'destroyed forever' as per Psalms 92:7.
The executional words from Jesus' mouth will rid the Earth of all wickedness -> Isaiah 11:3-4; Revelation 19:14-16, so there will be people alive on Earth at the start of Jesus' coming 1,000-year rule over Earth, and then there will be people who will have a happy-and-healthy physical resurrection back to live life on Earth forever.
So, the ' wake up tomorrow ' ( coming millennial morning ) will soon be the fulfillment of Revelation 21:4-5 when enemy death will be No more on Earth.
