'Fire' in the Bible

each one’s work will be clearly shown [for what it is]; for the day [of judgment] will disclose it, because it is to be revealed with fire, and the fire will test the quality and character and worth of each person’s work.

But if any person’s work is burned up [by the test], he will suffer the loss [of his reward]; yet he himself will be saved, but only as [one who has barely escaped] through fire.
