Yet, Jesus told Thomas, “Put your finger here; see my hands. Reach out your hand and put it into my side. Stop doubting and believe.” Thomas said to him, “My Lord and my God!” Then Jesus told him, “Because you have seen me, you have believed; blessed are those who have not seen and yet have believed.” (John 20:27-29)
In Christianity, it's not "seeing is believing, it's believing is seeing"!
In a way it’s experimental perception... just as we now know there is such a thing as radio waves and a whole lot about how they behave. But nobody ever saw a radio wave. So nobody’s asking you to craft some make believe picture. Instead they’re asking you to exercise your spiritual sense.
