The sun's surface looks like an ocean... A lake.. And it contains sulfur. ALOT of it.
Rev 19:20 "And the beast was taken, and with him the false prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone."
brimstone = sulfur
Jude 1:13
Quote:Raging waves of the sea, foaming out their own shame; wandering stars, to whom is reserved the blackness of darkness for ever.
The sun's surface has raging waves like those of an ocean, and space is pitch black

just saying
also if you say "but why have you hidden this from me ?"
God can say "On the contrary I had this in your face the whole time, you just failed to realize it."
He most likely said let me place it in your plain sight for your whole life so that when you learn what it is, you shall believe.
What do you think?
