Yes, in a way that they can relate.
BUT and this is a crucial BUT, we have to be careful as to WHICH voice we are hearing, there is only ONE voice and that is the voice of Christ and that voice CAN NOT lead to pain, fear, hate, intolerance and can ONLY lead to love.
Any othe voice is to be disregarded.
So your solution to conflicting answers to prayers would be that they are not hearing JEsus voice, they are hearing someone else's...whoever that is, and why Jesus can't make himself heard over them, I suppose we'll table for now. It seems odd that this sort of "love-checking" is necessary. The process ought to go, ask Jesus a question, get an answer. But in your solution, you've got to ask Jesus something, get an answer, then love-check it to make sure that this is actually an answer from Jesus and not some imposter-deity who is flitting about giving misleading information.
Obviously the possibility still exists (on possibly trivial matters) that believers can ask for answers, receive two different answers from alleged-Jesus, both answers pass the love-test, but they do both conflict. Therefore the four conclusions still stand, someone is lying, or someone is just making things up, or Jesus is messing with his followers.
IF you're all worshipping the same guy and IF you all purport to communicate directly with him THEN there should not be this conflict of opinion on even the smallest of matters. If the conflict exists, you're all either not worshipping the same guy, not having actual communication with him, or you're all just making it up. Trying to twist your inability to agree into some sort of virtue is just special pleading.
