Matthew 24:22 “And except those days should be shortened, There should no flesh be saved.”
Saved, means: to protect.
Jesus was speaking of His brethren, the 144,000. These will be gathered from the twelve tribes of Israel. This, is the flesh that will be saved, the reamaining, will be persecuted, some martyred because of their, testimony.
Only those who were born from the seed of God will make it to the very end of the tribulation period.
Revelation 6:9-11. These die before Great tribulation begins, their brethren and fellow servants die after. When the last two prophets are killed, then Jesus will return and Make war on those who killed them. Those who kill these servants of God, will be thinking they do God a service. They have been completely fooled, and will forever regret their mistakes.
When Jesus comes back and delivers wound to the beasts head that the dragon gives his power, his seat, and great authority to, He leaves for 3 1/2 years. This is the time the period given to the beast to continue. When the beasts time is up, and after the dragon kills the last two prophets, then Jesus returns. He destroys the armies gathered against Him with the sword of His mouth, and the fowls of heaven will eat their flesh.
He casts the beast and the false prophet into the lake of fire, chains the dragon, casts him into the bottomless pit for a thousand years.
Sends his angels out and gathers out of His kingdom all things that offend, and them which do iniquity, these will be gathered and burned in the fire. These that are gathered are the devils children.
The remaining will be gathered before Him and separated, the Goats, from the Sheep. These are the remaining living people after all this death and destruction. They have made it this far & have not worshiped the beast, or received his mark, if they had they would have been rounded up already.
Jesus said if your name is not written in the book of Life, you will worship the beast, so that means these who make it to the very end are the ones whose names are written in the book. But, even though you make it to here, if you are not one of those who helped Jesus brethren in their time of trouble, then you will not make it, you will be a castaway, your name will be written out of the Lambs book of life.
The sheep are saved because they helped Jesus brethren, and fellow servants in their time of trouble, These people don’t even know why they are being saved, incredible. The others didn’t help Jesus brethren in their time on need. These will go into everlasting fire prepared for the devil and his angels. These who make it to the very end are Gods own children, descended from Abel, the only begotten son of God. Some make it, some don’t.
