The issue is I want to believe. I pray for whatever is out there to reveal themselves to me.
However a "feeling" does not prove anything. An event that is pure coincidence that many would say is Divine does not prove anything. A vision, dream or illusion does not prove anything. These could be psychological tricks. I want that feeling that some have that they are truly convinced they have been saved. Even still, whats to stop that feeling from being a psychological trick? That is my problem with having to have 100% unquestionable faith. As others have said, God could easily use skywriting, or have one of each of his myriads of angels appear in front of every human, then there would be no doubt.
Even scholars debate the existence of Jesus outside the context of the Bible.
How am I supposed to ignore logical explanations and information and deny it and attribute it to the Divine?
