"For other foundation can no man lay than
that which is laid, which is Jesus Christ.
Now if any man build upon this foundation
gold, silver, precious stones, wood, hay,
stubble, every man's work shall be made
manifest; for the day shall declare it, because
it shall be revealed by fire; and the fire shall
test every man's work of what sort it is."
1 Corinthians 3:11-13

Of these materials, gold, silver, precious stones,
are comparatively fireproof. But the last three
wood, hay, stubble, are gone in the fire, poof,
just like that!
