Resist until you shed blood

I've been reading through the Bible on YouVersion using their one-year Bible plan.  Last week I was reading Hebrews 12 and came across this:

In your struggle against sin, you have not yet resisted to the point of shedding your blood.  Hebrews 12:4

Wow.  I think about how often I barely resist at all.  Particularly if the sin is something that can happen very quickly (words and thoughts fall in that category).  I want to keep this verse on my mind so whenever I am tempted, I can be reminded of this call to stand strong.

I love that it says resist until the point of shedding blood, because it really brings out the battle mentality.  I can't help the fact that stuff like that fires me up :)
