The Holy Spirit "will teach you all things and will remind you of everything I have said to you" - John 14:26. However, the Holy Spirit, apparently, will not remind us of everything Jesus said, since those things don’t directly apply to us. Or if he does remind us, it is not so that we will need to do anything about the things he is reminding us about. Or maybe those words were for the authors of the gospels only, so we don’t need to be reminded of them. It’s all very confusing. Maybe I’m just gnostically challenged.
