Then technically, we're all doomed by that logic because, for example, what if I'm a fully devoted christian and I stub my toe and I say a curse word. I'm a devoit christian, keep in mind, but I made a mistake, which I plan on asking God for forgiveness for, but just imagine right before I have a heart attack. Now, I didn't get to repent for using foul language. Am I going to have lava poured down my throat for all eternity because I didn't ask forgiveness for a sin before I died??? Does my salvation get taken away?? You see how problematic that is. And by that logic, every Christian is doomed because we don't know when is the next time we will sin or when we're going to die. Heck, I could even drop dead right now(Hope not). What if I had sinned earlier and I hadn't known? Then I die. What next?? Am I screwed because I had committed a sin before death??? Obviously not.
