The Lord protects His own. No matter what happens in the physical realm we have His salvation. And He will allow the world to go on until the last person who will not reject Him has been saved.
I do think the events of Revelation will happen someday, though, and they involve great suffering and extermination of those who won’t accept the mark of the beast. A quote I keep remembering is “This calls for patient endurance on the part of the saints”. It will look for all the world as if the Lord has abandoned His people, and if Satan was winning. But as long as we have the Lord’s salvation the worst Satan can do against us is send us Home.
I don’t know what will come during my lifetime, or how long my lifetime will be. But I do know that God is faithful. To live is Christ; to die is gain. It’s a win-win, no matter what happens. I’d like my kids to be able to build a life here, have a family, and walk humbly with their God here on earth, but no matter how or how long they live here, to live is Christ, and to die is gain. We will trust and wait.
