Peace all..
Revelation 21:4 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.
I believe that this verse has to do with those taken in the rapture. After a single tear shead, the Lord Almighty will wipe our emotions clean in Heaven.
The reason for this is because those of us taken in the rapture will see some of our loved ones who are still on earth to suffer the tribulation.
Peace and Godspeed
Pray for Israel
