Revelation 21:4 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.
Christians have shed many tears throughout the ages— especially in times of persecution— and tragedy.
Finally, in the new earth, all tears will be wiped away by God Himself and the former things will not be remembered, nor come into mind —Isaiah 65:17–19
You will be in the joy of Christ’s presence forever— Psalm 16:11 in your presence there is fullness of joy; at your right hand are pleasures forevermore.
