Does 2 Timothy 1:9 prove the Doctrine of Election? 2 Timothy 1:9 states:


  Who hath saved us, and called us with an holy calling, not according
  to our works, but according to his own purpose and grace, which was
  given us in Christ Jesus before the world began.


If this verse says what I think it does, that we were chosen to be saved "before the world began," doesn't that prove the Calvinist Doctrine of Election?
No. Even as a Calvinist, one has to understand that it takes more than one verse to put together a complete picture of how we understand salvation to work. The verse you reference in Timothy is indeed very helpful, but it really only proves the part about his purpose as the author of salvation was conceived before we were.

In order to defend the doctrine of election, you will need to reach out to other parts of scripture. For example in 2nd Timothy, how do you know that "us" is specific to individuals and not just representative of a general group of "somebodies" that God planned on saving?

I do think the doctrine can be defended from Scripture, but I don't think you can do it from one verse. You need to take into consideration the whole counsel of Scripture.
