Yes Christians are being persecuted and murdered as we speak in many Islamic countries, and it will get worse during Tribulation Period. Jesus didn't want his faithful children to be left in the dark regarding the upcoming events of the rapture and Tribulation Period. He gave all of this info to Apostle John in Book of Revelation and He gave a promise not to allow His faithful to become part of the worst event in the history of mankind called Tribulation Hour. It is all there in Book of Revelation, from Jesus Himself. What I find ironic from post-trib is that most of their info regarding the rapture and tribulation, are mainly from other Books of the NT and speakers. Why not just get the info from the source Himself, Jesus Christ. If you get a chance please read Revelation 3:10 and ponder on it for awhile. When the Church is raptured, the Judgment Seat is initiated to judge each Christian for all the good & bad deeds they have done; and the bride & bridegroom (Church & Jesus Christ) will get married and have their honeymoon on earth during the Second Coming. Good Luck with your journey.
