The one who stands firm to the end will be saved

Mark 13:1-37
The sign of the end days!
The one who stands firm to the end will be saved.
False messiahs and false prophets will appear and perform signs and wonders to deceive, if possible ,even the elect. So be on your guard; I have told you everything ahead of time.
Heaven and earth will pass away, but my words will never pass away.
But about that day or hour no one knows, not even the angels in heaven, nor the Son, but only the Father.
Watch! , keep watch! is our lesson in life.
Some of the language Jesus uses and the things he describes echo Old Testament prophecies of the end-time and the symbolic language of 'apocalyptic' writing, familiar to his hearers; for example, verse 7-8 battle, earthquakes, famines and 24-25 eclipse of sun and moon...
Why?
Jesus encourage his disciple and his followers that what will happen in the future. The most important is to watch the false teaching and false sign of wonder.
No one know what is the date and hour of the end of the world.
Stand firn on the truth then we may be saved.
Their question had two parts and so required two answers. Jesus combined those answers into one long discourse about what was ahead before He returned. Some of those prophecies were fulfilled with the destruction of Jerusalem in AD 70. The remainder has yet to happen.
Because of the increase of wickedness, the love of most will grow cold, but the one who stands firm to the end will be saved. And this gospel of the kingdom will be preached in the whole world as a testimony to all nations, and then the end will come.
Those who endure to the end and are saved will stand firm through ridicule and hatred. Matthew 24:10 says that when many turn away from the faith, they will “betray and hate each other.” With the proliferation of Internet websites, blogs, and Facebook pages, we are seeing the polarization of opinions leading to angry diatribes and un-Christlike dialogue. Everyone has an opinion about everything, and opinion, it seems, has become a god worth defending through anger.
How?
Trust in Jesus word and with his love, stand firm in any situation will be saved.
