To
envision is to picture to oneself. As youve noted, to envision something is to imagine it. You picture the messages from your God in your mind so you are envisioning or imagining whatever it is you think your God is telling you. As soon as you claimed you converse with the supernatural (beyond the visible, observable universe) you precluded any chance that it could be present to your senses or observable in any way. Consequently, not only are you imagining the messages, but your God also is not present to your senses and you have never before wholly perceived it in reality.
Suppose I told you I receive inaudible messages from Santa Claus and as evidence supporting my belief, I claim to have visions. Would it be reasonable to say I was credulous?
You claim you receive inaudible messages from your God and that the evidence supporting your belief is your bare assertion that you have visions. Im simply observing that you are ready or willing to believe, especially on slight or uncertain evidence.
