Dispensational Pretribribulationism is more of a system than a scattered source of proof texts. Typically one main point is that the church is mentioned throughout the first three Chapters of Revelation, and then not again until the end of the book of Revelation. Many others as well, that the Church was not started until Acts Chapter 2. Also that the entire Old Testament does not refer to the Church, but to Israel.
Incidentally most Jews I have spoken with are much less "offended" by Dispensational Premillenialism as it, at least, allows the Old Testament to keep its original meaning.

Grace is not common.
