1 Corinthians 3:14-15

If any person’s work which he has built [on this foundation, that is, any outcome of his effort] remains [and survives this test], he will receive a reward. 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. [Job 23:10]
