Our Lord says that the Gospel will reach the entire world AFTER the worldwide persecution.
He also says that many will leave this faith. If you are going through tough situations right now, maybe God is preparing you so that you will not make such a fatally wrong decision to leave him. Rejoice that your name is written on the book of life.
If you are thinking persecutions only happen in Asia and the Middle East, be prepared to be surprised. Jesus said "all nations." Look at the signs, things are happening just like Jesus our Lord has told us. I am not even prophesing, I am just quoting his prophesy. Rejoice that your name is written on the book of life.
These things should even set us on fire for the love for the Lord and preach like there is no tomorrow because Jesus said that many will leave this faith but - *somehow* and on the contrary - that is when the Great Commission will be completed and our master will come back. Rejoice that your name is written.
So when we see these signs our reactions ought to be to rejoice, to be excited for His return, and to preach even more passionatelly.
