But before that Spring day in 2008, I believe there will be a great outpouring of the Holy Spirit, which will cleanse and purify the Bride of Christ: Daniel 12:10

Allow me to speak only in the context of myself here, lest we get into a heated dispute over this.

I KNOW that I am redeemed, and I don’t have to guess about it. The definition of redemption means that I am part of The Bride of Christ and The Holy Spirit has been given to me as an engagement promise.

I am NOT being referenced in Daniel 12:10. This passage has everything to do with the Great Tribulation and nothing with me.  The raising of the Old Testament saints you mentioned takes place at the end of the Great Tribulation.
 
If I may suggest an excellent Hebrew teacher who is redeemed (that you can look into), David Hocking, who can be found at www.davidhocking.org , he has many superb teachings that discuss the issues you are mentioning.
 
The only way I am going to be purified completely is to die or be taken out of my body of flesh. I was as holy and indwelt by The Holy Spirit as I will ever be (while in my sinful body) the instantaneous moment that I was redeemed. I also received whatever spiritual gifts that Jesus gave me at that instant as well.  There is no way for me to “get cleaner” by any effort of my own. That would put me under The Law, self-effort, which is death. I may never discover all that has been given to me as a result of that moment of redemption while I am in flesh, and that is my shortcoming.

I do not discern First Thessalonians describing redeemed people “floating around” somehow and waiting for resurrection. Several of the “religious” groups that I find abominable subscribe to this theory, so I reject it.  Not preceding to me means that if a redeemed person’s flesh dies, then they are resurrected before those who are taken in the rapture, or translation. First Corinthians 15 refers to the death of the flesh body as well, the resurrection of redeemed people who die of physical causes.

I find a mixture of Old Covenant scripture with Grace to be completely depressing, destroying my joy and plunging me into religious distress, which took me decades to get out of. The thought of going through some kind of testing that is described in Daniel 12 for people in The Great Tribulation  is opposite to everything I have already been given by redemption.
