“He will wipe away every tear from their eyes, and death shall be no more, neither shall there be mourning, nor crying, nor pain anymore, for the former things have passed away.” Revelation 21:4
All these things are passing away. That means you will not find or experience them in the new heaven and earth.
Nobody in the new heaven and earth will ever die. No one will grow old. No one will become sick or ill. There will be no need for hospitals or for emergency services. You will never attend a funeral there.
Jesus said, “I am the resurrection and the life. Whoever believes in me, though he die, yet shall he live” (John 11:25), and “Everyone who lives and believes in me shall never die” (11:26). Because there is no more dying, there will be no more mourning, no more saying goodbye.
There will be no more aching bones! The resurrection body is made of flesh and bones (Luke 24:39), but the flesh will not wrinkle and the bones will not ache.
Nothing in your future life will bring you sorrow, fear, sadness, or disappointment. When you share this life of joy, nothing will ever happen that would cause you to cry. What about tears from the past? There are tears on earth that even those who love us most cannot wipe away. But God will wipe every tear from our eyes.
In your experience of death, pain, and tears in this life, soak in these promises until they bring you comfort and hope.
