1. God is a Consuming Fire.
2. Fire destroys most materials like wood, paper, fabric, etc.
3. Fire doesn't destroy gold. Fire purifies gold.
4. True believers are like gold. They don't need money (mammon) to make them VALUEable.
5. True believers see gold as something they can walk on like streets (i.e. true dominion).
6. Mammon worshipping 'believers' would probably start mining the streets of gold if they get into heaven.
7. Judas Iscariot chose mammon and had an undesirable end.
