First of all, the title says Meaphysics?? I believe the word is Metaphysics.  Something that was not mentioned in this topic was the Bible.  It is and will always be, "God Breathed".  which basically means All of the books of the bible were God inspired through the people who wrote each book. 

Since we are "mere humans", as you stated, though in a different manner, we think and do as do humans.  It takes the one who created us (God) as we open ourselves to him, by our own individual choices, to allow for a God and Mankind relationship to take place.  That is the vertical portion of the symbol of the cross.  Then we allow ourselves to learn of Him through much biblical study and a community of believers to share what we have learned with the world.  That is the horizontal portion of the cross.  This will, in time lead to  our Salvatiion.  Metaphysics was established by humankind, however God created humankind, so goes the "Circle of Creation".  You speak very elequentley indeed.  Is Metaphysics important, of course it is and a special field indeed.  When you used the word "revelation", were you meaning how the information is relevant to each other, or perhaps you were speaking of "Revelation", the final book in the bible which speaks of the second coming of our Lord and Savior Jesus Christ, as well as what is to take place during this time?

Metaphysics is Metaphysics because God created the people to bring for Metaphysics, as he gave them a brilliant mind to study and identify, or perhaps..create it.  Our God is so awesome, amazing and compassionate.  That is not to say difficult and sometimes ugly things happen on this earth.  We don't know why, but Christians who are living their faith trust in this awesome a powerful God who gave His son..His ONLY Son for our Sins..all of us so that we may seek forgiveness, pray for redemption and be FORGIVEN AND REDEEMED AFRESH every moment of every day we are on this earth.  After all, we are only passing through.  God's Blessings to you and may you be touched my the heart of Him who created you.  Thanks for taking time to read this and have a beautiful day.
