Summary: David tells God to protect him from his enemies. In return, David will praise God wherever and whenever.
Response: Again, even knowing that David and I are different beasts, I spent the whole psalm going "nope nope nope." Telling God what to do, more us vs them (including "I'm perfect" and "kill them"), making praise conditional... The list goes on. I'm trying to find a pivot here. The best I have is that I'm sure I'd say much of the same if I was actually in the life-or-death situation David was in.
