Galatians 2:8 is another verse that has always been difficult for me to understand. What exactly does Paul mean by "For if I rebuild what I have once destroyed, I prove myself to be a transgessor". I've read several commentaries on this verse, but they usually don't say too much about it. What is the thing that was once destroyed and how is it rebuilt? I would assume that the destorying is related to sin and the rebuilding is related to Christ, but it's difficult to pin it down. Also, how does the rebuilding process prove one to be a transgessor of the law or is the destroying part that proves one to be a transgessor? Is it the fact that something needs to be rebuilt at all that proves one to be a transgressor?

Thanks,
John
