What confuses me is this. The bible mentions the blood of Jesus. Christians also often use it and plead the blood but where and how do they know when this is helpful and when not? Who tells them what the blood is good for? I feel like they have this not from the bible but from christian authors which base their knowledge on extra revelations which they claim to have gotten. Where does the bible say when to plead the blood? The problem is if I try to do something like pleading the blood but at the same time I'm not even sure wether in this situation this is even the right thing to do then it doesn't make sense. As an example: Antibiotics can be very helpful but if you take antibiotics against everything then it won't help, they only help against special things. And isn't it the same with the blood of Jesus? I don't think that you can use it in all situations.
