The answer is not so simple as I thought. Besides I always have so much to say!
Almost everything in the entire Bible is SPIRITUALLY discerned.
Jesus taught in parables so that his listeners in public would NOT understand a thing He was saying. He had to teach the meaning of these parables to His disciples in private.
"Therefore speak I to them in parables, because they seeing, see not; and hearing they hear not, neither do they understand. And in them is fulfilled the prophecy of Isaiah… for this people’s heart is waxed gross, and their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with their eyes and hear with their ears, and should understand with their heart, and should BE CONVERTED, AND I SHOULD HEAL [SAVE] THEM" (Verses 13-15).
God cannot just show up because we are not ready for Him. Parables are Words of Spirit which most do not understand...But we will...
"And so it is written, The first man Adam was made a living soul; the Last Adam [Jesus Christ] was made a quickening spirit. Howbeit that was not first which is spiritual, but that which is NATURAL; and afterward that which is SPIRITUAL" (I Cor. 15:45-46).
"It is sown [first] a NATURAL BODY [a physical body which dies]; it is raised [afterward] a SPIRITUAL BODY [which is made immortal and never dies]…" (I Cor. 15:44).
"Who shall change our [first] VILE BODY, that it may be fashioned like unto His [afterward] GLORIOUS BODY…" (Phil. 3:21).
"If I have told you EARTHLY things [first], and you believe not, how shall you believe, if I tell you of HEAVENLY [spiritual] things [afterward]?" (John 3:12).
This goes in cohesion with what I said in the last post...
Though a note of warning [contrary to Christian belief] this does not mean we go to Heaven when we die (no, I am not a JW). Only that which came from Heaven goes to Heaven.
