Kaylee, a lot of people are fearful of the end days because there has been so much disagreement over what the scriptures say and what the actual meaning is of the images shown in Daniel and Revelations. Of course, the reason all of that is so vague and cryptic is so we won't be able to determine the day our Lord will return.
My personal belief on when it will happen is this: when God, Who knows all men's hearts and their future choices, sees that there is no one else who will accept the message of the cross, the rapture will occur and His attention will turn toward Israel. I may be way off-base with that belief, but that's what I think. As long as our hearts are right with Him, we have nothing to fear; for He will protect us.
In fact, I think that's the purpose of the rapture - to catch away His church and protect them from the bad times that will come.
