Looking at a cross section of our planet,

some years ago.  (Shoulda kept that magazine :/ )  The drawing showed, about halfway in - between the lower mantle and the upper core - a boundary of solid rock.  At that depth (some 2,000 miles) the hot temps and pressures squeeze the rock into something like really thick paste.  But the drawing showed some 100 miles of solid rock - which is likely iron, or nickel.  In junior high, the text book said, our earth's interior is about 75% nickel and 25% iron.

But wait a sec, in order for convection to work, there has to be transference of magmas.  How would such move past the barrier?  Bars anyone?  Think of a factory that makes prison bars, loaded willy-nilly onto an eighteen wheel  flatbed.  Some 100 miles of bars, but the "cooling" magmas will move down, displacing the hotter ones to move up - or is it the other way around?  

Anyway, seeing that illustration gave me the willies.  Don't recall whether that was before 2010, (when having realized i was a sinner, and on my way there) or afterward.  Both modern and ancient pagans know, God judges the wicked, and the sentence is eternal, and horrible.  

"I went down to the bottoms of the mountains, the earth with her bars was about me for ever: yet hast thou brought up my life from corruption,  O LORD my God."  Jonah 2:6

"And I say also unto thee, That thou art Peter, and upon this rock I will build my church: and the gates of hell shall not prevail against it." Matthew 16:18

"As for the earth, out of it cometh bread : and under it is turned up as it were fire." Job 28:5

"That the wicked is reserved to the day of destruction? they shall be brought forth to the day of wrath." Job 21:30
