God has two fires!
(Thomas Watson, "The Beatitudes" 1660)
God has two fires:
one where He puts His gold,
one where He puts His dross.
The fire where He puts His gold, is the fire of affliction — to purify them.
"I have refined you in the furnace of affliction." Isaiah 48:10
The fire where He puts His dross, is the fire of damnation — to punish them.
"Away with you, you cursed ones, into the eternal fire prepared for the Devil and his demons!
And they will go away into eternal punishment!" Matthew 25:41, 46
