When will these things happen? By standing firm you will gain life

Luke 21:1-19
This poor widow has put in more than all the others. All these people gave their gifts out of their wealth; but she out of her poverty put in all she had to live on.
The time will come when not one stone will be left on another, every one of them will be thrown down. When will these things happen? And what will be the sign that they are about to take place?
When you hear of wars and revolutions, do not be frightened, These things must happen first, but the end will not come right away. Nations will rise against nation, and kingdom against kingdom, There will be great earthquakes, famines and pestilences in various places, and fearful events and great signs from heaven.
But before all this, they will lay hands on you and persecute you. You will be betrayed even by parents, brothers, relatives and friends, and they will put some of you to death. All men will hate you because of me. But not a hair of your head will perish. By standing firm you will gain life.
Why?
Jesus looks on the heart of everyone. It is not the amount of devotion, but the heart who concerning.
When and what if the end day? There are many sign will show to us. It is caused by climate change.
Before that they will lay hands on us and persecute Christians. It is on going now. Jesus tell us standing firm we will gain life.
Devotion of the widow is her faith on the Lord, but about us have such faith to the Lord.
How?
Be faithful to the Lord, God is my way and my portion. God will not forsake us when we trust in Him.
