Good Guys and Bad Guys

I've never posted about politics here, so brace yourself!  I'll keep it short.

In response to the current debate on guns, an NRA official said:

"The only thing that can stop a bad guy with a gun is a good guy with a gun."

This statement is the opposite of the gospel.

The gospel says there's one category, and we're all in it:  bad guys.  Everyone believes they're a good guy.  Or, as the Bible says it "right in their own eyes" (Prob 21:2).  Christians, especially those with guns, should not view themselves as the good guys.  But rather, the bad guys who were rescued, and are good, solely but for the grace of God.  Our judgements are not always just and motives not always pure.  If this is true for Christians, how much more is it for the world at large?

"The only thing that can stop a bad guy with a gun is a bad guy with a gun."

Less convincing as a rallying cry, but far more honest about the consequences.
