Explain ? I feel like I need to fight, instead of wait. Is that unbiblical?
"The rapture" is a term that is most commonly used in association with the Dispensationalist teaching that at some point Jesus is going to take Christians into heaven prior to a period of major tribulation. There are variations of this teaching, for example that this event happens mid-way through this tribulation, and others that it will happen afterward. These views are often described as "pre-tribulation rapture" (before) "mid-tribulation rapture" (mid-way), and "post-tribulation rapture" (after).
Historically, however, the idea that Jesus is going to remove Christians from the earth in a massive exodus like this is entirely foreign. The historic position is that when Jesus returns, He returns in glory as judge of the living and the dead--so He comes in judgment, and when He comes the dead are raised, and those alive at His coming share in the same glory of the resurrection, as St. Paul says, "We shall not all die, but we shall all be changed". The Lord comes, the dead are raised, there is the final judgment, and God makes all things new. There's no "rapture" at all in the historic Christian teaching. The idea of "the rapture", as popularly conceived, dates to the early 1800's, to an Irish preacher named John Nelson Darby.
Darby became prominent among the Plymouth Brethren movement, and his and their teachings ended up attracting a bit of attention with some notable figures, the apostles of Dispensationalism in the United States include Cyrus Scofield (whose Scofield Reference Bible included Dispensationalist commentary and interpretations in the margins, his reference Bible became one of the most popular in the US for a time) and Dwight L. Moody.
In the late 19th and early 20th centuries several Dispensationalist seminaries and Bible colleges were opened with the express purpose of teaching the Dispensationalist interpretation of the Bible, of these are included the Moody Bible Institute and Dallas Theological Seminary. These Dispensationalist schools became the breeding ground for successive generations of Dispensationalist preachers and theologians, and their influence largely came to shape and dominate in American Evangelicalism; it was this fertile ground which gave rise to a number of popular Dispensationalist works, such as Hal Lindsay's Late Great Planet Earth in the 70's and 80's, and Tim LaHaye and Jerry Jenkin's super-selling Left Behind series of novels in the 90's and 00's.
Mainline Protestant churches have been much more resilient against Dispensationalism, but Mainline Protestantism is less visibly present in America than it used to be, and Evangelicalism has become far more prominent in the US (culturally and politically) with the rise of the Moral Majority and Religious Right in the 60's-80's as well as the Jesus People Movement of the 70's.
