Qu'ran questions, part 1

In my readings of the Qu'ran I have come across many passages that confuse me or bring up questions. This will be the first post in a series designed to enable you to help me understand the intent of the Qu'ran better.

QUESTION 1.
If God/Allah is one (and not a Trinity, as Christianity teaches), then why does He refer to Himself as "We" in the Qu'ran? (see S. 2:34, 2:38, 4:47, 6:9, and many many other places)

ANSWER:
The "We" here is the "Royal We:" it does not indicate the plural, but instead is a mark of the highest respect. The answer is found at http://www.godallah.com/we_and_he.php
