If there is a tribulation of the saints in the future that will be terrible persecution worldwide that is the worse ever in the history of mankind,not that the persecution will be greater on an individual level,for persecution is persecution,but it will be on a bigger scale affecting all Christians,and not only certain areas like now,do not worry about it.
Sure it sounds scary,and we might fear it,but if you are on God's side in the truth,your attitude will be different,for when it comes,and you are being persecuted the Holy Spirit will come upon you,and you will not care about their persecution for you will have the courage,and the strength,to endure it,and be like Paul that basically said,bring it,do not sing it,for he said I am ready to depart from this world having done what the Lord sent me to do.
We will fear it now,and rightfully so,but do not worry,when it comes your attitude will be different,and the Spirit will get you through the persecution like the Spirit got Jesus through the persecution,and cross,and God can comfort,and lessen the pain,of their persecution,which I believe God will not allow them to torture the saints,but it would be quick,and we will be with Jesus,for when the world gets to that time,they are of the occult,nature worship,acknowledges no personal God,but honor the God of forces,or the power of nature,which they are in to spiritual evolution through nature,so they are not going to play around with people that oppose them,but they want them off the world fast,and will not toy with them,because that is their attitude for the world is all they have,and know,so they will want them off their precious earth fast.
The Bible says the saints shall be hated of all nations,and the Gospel must be preached in to all the world for a witness unto all nations,then the end shall come,which then comes the end when the Son shall have delivered up the kingdom to the Father,when He shall have put down all rule and authority.
Since Jesus did not put down all rule and authority on earth,and the saints have not been gathered unto Christ,the end has not come,so it appears that there is a persecution of the saints that will happen in the future that will be worldwide for they shall be hated of all nations,and the Gospel must be preached in to all the world,which could of not happened years ago,for the Gospel could not reach that far at that time.Mainly by technology it is possible for the Gospel to be preached in all the world,which the book of Daniel will also be able to be understood in the end time because of advanced travel,and advanced technology,for the saints can hear and see what is going on in the world,therefore understanding the end time of how they can come together and rebel against God,and persecute the saints.
So be of good cheer,and do not worry,for we might fear now,but when it comes,if you are there,it will be a whole different attitude upon you when they persecute you,and it will not bother you for you will be so strong in the Lord,for the Spirit will toughen you up,and God can comfort,and lessen the pain,of persecution.
