I'm willing to stick my neck out a little here. I think the underlying questions bring out an important point; and that is there much more to Christianity than dogmas and traditions, and debates on various issues.
It speaks to the bigger question: Is there more to life than doughnuts? So, I don't take it that the questions stop at a specific interpretation of what "Realm means" or "enlightenment".
The scripture I quoted from Ephesians specifically uses the term "enlighten" that Paul's prayer was that we would live in a place where Revelation was not only possible, but a way of life, in reference to comprehending mysteries that are hidden from mankind, including other Christians. How could Paul have known that we would judge the angels, if he didn't have revelation? Where does one come up with such things? How can Paul comprehend that human submission to authority is a sign unto the angels? Hmmm? Does anyone here know how? Does anyone here know what this means?
Does anyone know that Job chapter one was not just about humans, but also about angels??? What was the message in Job that applied to the angels, and not just men?
Is the Bible only about humans then? Why does the Bible tell us that we will judge angels? It isn't about angels, it's about us realizing the value of the place of honor our God is giving to us, and also to realize that in our dealings with others we shouldn't be so petty.
When Paul says in Romans 8, that if God the Father did not withhold his son from us, will he not also give us ALL THINGS besides; can we know what this means apart from revelations? What are "All THINGS" and how does that apply to our lives? It means so much more than most realize it means.
So, when the Bible says "Eye has not seen, ear has not heard, nor has it entered into the hearts of man..." it didn't stop there. The scripture begins by saying that there are so many truths and mysteries beyond all we could possibly imagine; but then the scripture says that the Spirit of God reveals these to us--- or I should say it happens to those who are willing to seek, ask and knock.
Christianity should be a religion that is far more dynamic than bake sales and hoping we guessed right about God's love and the hope of eternal life.
It's actually about getting to know God in this life, in this here and now. It is about experiencing that love, and tasting it (as Peter said). So many Christians don't know there is a "More". Others have experienced "More".
And so, this question asked is really at the core of the most profound of questions, one that King David spoke of in the Psalms: God knows us inside and out, our comings and goings, who thinks about us and who is actually active in our lives, even when we are oblivious to this.
But what about those who want to come into his gates, his courts- "I will enter his gates with thanksgiving in my heart...I will enter his courts with praise..."
Well, this is far more than a song, it is actually a formula for entering a deeper walk with God. Thanksgiving- which is fostering the attitude of being attentive to the gifts God has given us, will bring us closer to God- his gates. If we learn how to praise- which transcends thanksgiving. It is coming to the place where we actually see and appreciate God's motives, his love for us, his wonderful attributes, we actually have the capacity to enter into a place where we see and hear and understand things we were once blind to.
God is always near in the sense of being able to hear and understand our needs; but our sense of that reality is blurred. Through changes in our hearts, we have the ability to "know God"- what Jesus was talking about in John 17:3- Fellowship.
In Revelation 3, Jesus said, "I stand at the door of your heart and knock...if any man hears my voice and opens...I will come in..."
This is wrongly used at altar calls spoken as an appeal to non-Christians to consider Christianity. Jesus was speaking to lukewarm Christians here, Christians that thought they could see, but were spiritually blind. In other words, Christians can close their doors to God. They don't necessarily have a clue who he is or how much they are missing, or how close God wants to be to them.
So, in this sense, talk of different planes or realms is appropriate, however it is phrased it is a valid question that I interpret- "Is there a whole lot more to this thing? Can Christians live in the supernatural- experiencing a taste of heaven here on earth, knowing the actual feeling of God, being physically and spiritually touched by God here and now?
The answer is obvious to those who know there is more, and it is speculative to those who've never seen it. It is doubted by those who are cynical, just as Thomas doubted Jesus really rose from the dead. But I think it is absolutely great that someone is asking the question.
