You need to purchase a book
the author is RENALD SHOWERS
The book is titled, MARANATHA! OUR LORD COME!
It takes too long to retype his points, but I guarantee you, God never told His peole to expect tribulation unless He was expecting His people to expect tribulation, as He did warnign Israel of their need to repent many times.
The Bible NEVER tells Christians to expect a coming judgement, especially one that lasts 7 years and culminates in His return, the bible is silent on any such idea
Buy the book, I guarantee you will find it important.
As for the elect, Showers covers that, too. I believe Jesus was referring to a time different than the rapture
2.The word "tribulation" occurs 21 time in the KJV: Only 4(!) times it refers to the last days (Matt 24:21 & 24:29, Mark 13:24, Rev 7:14). The iother times it refers to the suffering of Christians! Read John 16:33 for Jesus plain warning of coming tribulation.
3. In the NT, Tribulation ALWAYS refers to the suffering of the saints! Look it up! It NEVER refers to sufferings of non-Chsristians.
4. Read the scriptures for yourself, don't follow someones "teachings", especially if the scriptures teach the exact opposite of what the "teacher" asserts!
