As I was doing the reasearch nesessary for this, I found an article by an excellent writer. It then became clear to me that since I really did not have that much to add to what he said I decided to share some of his ideas with you.
The following is from Kyle Roberts, Assistant Professor of Systematic Theology and Lead Faculty of Christian Thought, Bethel Seminary (St. Paul, MN); he contributes articles to the "Evangelical" portal at the website 'Patheos'. He is one of the the theologians (along with Timothy Dalrymple) that I read to get a solid and honest intellectual view from the Evangelical perspective. In this article he himself quotes Jurgen Moltmann and N.T. Wright, two of the most respected theologians of the last 20 years; I was going to N.T. Wright's books myself as I was reflecting on this matter.
My dear reader, if you are an Evangelical and/or believe in the 'Rapture' I strongly encourage you to read this. Roberts presents his arguments in a reasonable and respectful way.
Rapture theology has captivated the contemporary public imagination. The most recent iteration was the popular Left Behind material. Prior to that, in 1970, Hal Lindsey's The Late, Great Planet Earth fascinated countless Christians. In contrast, contemporary evangelical theological scholarship found its voice, to some extent, as a counter to the sensationalist eschatologies of dispensational fundamentalism. George Eldon Ladd's influential work on New Testament eschatology moved evangelical theology away from a focus on literal fulfillment of end-times scenarios, especially literalistic readings of Revelation and "rapture" theologies connected to tribulation schemes. Yet within popular evangelicalism, fascination with the rapture continues to pervade preaching and teaching about the "end of the world." This is a problem.
Biblically, rapture theology finds its roots in 1 Thessalonians 4:15-17, with its language of being "caught up . . . in the clouds to meet the Lord in the air." N.T. Wright suggests, however, in Surprised by Hope,
When Paul speaks of "meeting" the Lord "in the air," the point is precisely not—as in the popular rapture theology—that the saved believers would then stay up in the air somewhere, away from earth. The point is that, having gone out to meet their returning Lord, they will escort him royally into his domain, that is, back to the place they have come from. (p. 133)
Moreover, while rapture theology retains the apocalyptic vision of the New Testament, it does so in precisely the opposite direction of the biblical authors (see Moltmann's The Coming of God, p. 159). Rather than seeing the apocalyptic as a reason to resist evil, rapture theology suggests that Christians are meant to escape this world and that the destiny of this world is destruction. In such a view, Christians will be swept off the face of the planet, leaving it to the devices of evil and the horrors of tribulation.
The biblical witness suggests exactly the opposite, that Jesus is already king and that his kingdom has already made inroads into this world, which will one day be ratified and confirmed (at his Second Coming). Tribulation is a past and present reality, and the church is called to endure it on behalf of the world and to stand up against it through the power of the Spirit. Rapture theology, in which Jesus will take his people away and leave the world to the devices and whims of evil, runs counter to the good news that the kingdom of God has already come in Christ (e.g., Mk. 1:14-15).
In contrast to rapture theology, a biblical eschatology:
1) Affirms the inherent value of the earth and motivates care for creation. Rapture theology suggests that we are "just passing through" this temporary dwelling place. Eventually we will escape this world and find our final home in an ethereal realm, a "heaven" filled with mansions and streets of gold. Again N.T. Wright helps to re-frame our expectations. God's plan is for "a new heaven and a new earth" (Rev. 21:1), what Wright calls "life after life after death" (pp. 148ff). Since the goal is the re-creation and redemption of thisworld, we have motivation to care for and cultivate it now.
2) Offers a compelling vision for resistance against evil, injustice, and all forms of oppression in the present world order. Rapture theology generates an "escapist" mentality whereby our best hope for dealing with injustice, wickedness, and hopelessness is to simply fly off to a perfect spiritual world unhampered by sin and finitude. Most harmfully, rapture theology sees injustice, oppression, and even natural disasters as predictive signs of the end of this life for Christians, rather than as the evil and discord they really are.
3) Redefines Christian mission as anticipation of and participation in the kingdom of God. Salvation, as Wright suggests, enables us to be witnesses to and signs of the ultimate salvation of the cosmos, as well as participants in that salvation (p. 200). That's why the biblical witness says that Christians are to be agents of reconciliation with those who do not yet know God and are to participate in the restoration of the cosmos (2 Cor. 5:20). In contrast, rapture theology suggests a sudden, disruptive end to that project, cutting off hope for reconciliation and renewal.
A de-raptured theology reorients evangelism and the meaning of salvation around the centrality of the kingdom of God. Rapture theology tends to use scare tactics—"Don't get left behind!"—that market individual salvation as an economic transaction rather than a new way of living justice, righteousness, and peace. A de-raptured evangelism is an invitation to embrace the reality of the Kingdom inaugurated by Christ.
Unfortunately, out of distaste for rapture theology, some Christians have swung the pendulum too far in the other direction. They focus everything on the present, believing that our world is what we make of it and that it is not only futile but even counter-productive to look to an apocalyptic Eschaton. Perhaps biblical eschatology resides not at either end of the spectrum, but somewhere in the middle. Only God can bring about the Kingdom, and Christians rightly await the second, and final, return of Christ (Col. 3:4). We look for his coming and long for the justice it will bring. In this sense, Christian theology should retain the apocalyptic (the hope that God is coming to make things right) without falling prey to fanciful notions ofapocalypticism.
America is a nation imbued with eschatological consciousness. It's often how we talk about hope, change, and how we motivate action in the present toward a better future. As such, American Christianity will always be infatuated by and prone to predictions about the coming end. The recent media preoccupation with the doomsday, rapture theology of a well-meaning but deeply mistaken radio broadcaster is just the latest example. Christian leaders have a responsibility to remind people that we cannot know the "day or hour" and that it is counter-productive to speculate about it. They should also emphasize, however, that Christians should not seek to escape the world, but to embrace and engage it instead.
