Here is my exegetical analysis of 2 Thessalonians 2:1-17 which will demonstrate the validity of the Dispensational/Premillennial perspective articulated by Paul.
UPDATE: Please see my revised exegetical analysis of 2 Thessalonians 2:1-17, which I go more into depth in some areas, and update (vs.3) to what I believe is a more biblically grounded position. My prayer is that this will be a blessing to you.
