Christopher777,
People have given you some pretty good advise so far. Those references Kepler gave you will get you started.
Another good recent reference that we have talked about before is the Book:
The Rapture Exposed: The Message of Hope in The Book of Revelation by Barbara Rossing. Since this area is a concern of yours, I would think the $10 or so to get a copy would be well worth it. She lays out the problems with some of the commonly accepted views of the endtimes, both theologically and in the damaging results that it produces in people's lives.
Dispensationalism has some major problems, but is so widely taught that it kind of has the field to itself and you've probably noticed that when one person in a debate talks they seem right until the other gets up and speaks and then you find there are all kinds of holes in their arguements.
For instance most dispensationalists are too rigid in their understandings of the dispensations if you asked them to separate the Law and Gospel in the Bible, they would just flip to Matthew and say it's right there that the Gospel starts, and what was before that was the previous dispensations. Well, the Apostle Paul would go in the synagogs and teach the Gospel from Scripture, the only scripture he had was what we call the Old Testament, the Old Testament contains the Gospel.
Or take this passage from Acts. NET Translation:
2:14 But Peter stood up
25 with the eleven, raised his voice, and addressed them: You men of Judea
26 and all you who live in Jerusalem,
27 know this
28 and listen carefully to what I say.
2:15 In spite of what you think, these men are not drunk,
29 for it is only nine oclock in the morning.
30 2:16 But this is what was spoken about through the prophet Joel:
31
2:17
And in the last days
32 it will be,
God says,
that I will pour out my Spirit on all people, 33
and your sons and your daughters will prophesy,
and your young men will see visions,
and your old men will dream dreams.
2:18 Even on my servants, 34 both men and women,
I will pour out my Spirit in those days, and they will prophesy. 35
2:19 And I will perform wonders in the sky 36 above
and miraculous signs 37 on the earth below,
blood and fire and clouds of smoke.
2:20 The sun will be changed to darkness
and the moon to blood
before the great and glorious 38 day of the Lord comes.
See right there you have none other than the Apostle Peter as recorded in scripture telling us that they were already in the last days, in other words the millenial kingdom. Amillenialism is not saying there is no millenium, it is agreeing with clear scripture that the millenium has already started. It doesn't make the mistake of taking the 1000 years as written in the least literal book of the Bible as a literal 1000 years but rather the way it was used in the culture of the time to represent a long time. So rather than denying a millenium, amillenialism says that we are living it.
In any case, I doubt that you will have much trouble with your views in a Lutheran church, generally there just isn't that much time spent on the end times prophecies. Now if you can't control yourself and you stand up and scream out the latest prophecy each week from the tv preachers, then you would probably have some problems, but I doubt it would come up much with the possible exception of if you were going to teach a class on the end times or certainly if you went to get trained to be a minister.
In the end, if you decide to stay dispensationalist, I would recommend at least studying progressive dispensationalism. It comes the closest to accepting scripture of the many flavors of dispensationalism.
