We believe that Jesus Christ will return, visibly and personally to establish his kingdom. When he returns we do not know. His return will mark the last day and a final judgement of all people. A new heaven and the new earth with be consummated. God will preserve and keep all who truly belong to Christ for this last and great day.
This means that the age we live in now, suffering under the consequences of sin, is marked by death, mourning, pain and suffering. This age will end and be replaced by a new age where God will wipe every tear away and there will be no more death or mourning or crying or pain. This will only happen when God sends Jesus Christ back to earth. There will be bodily resurrection of both the saved and the lost: a solemn separation will take place, the lost to everlasting punishment and the saved to eternal life with Christ. This day cannot be predicted, yet all people need to be ready for that time.
