If the work that anyone has built on the foundation survives, he will receive a reward. 1 Corinthians 3:14

“If anyone builds on the foundation of Christ using gold, silver, costly stones, wood, hay or straw, his workmanship will be evident, because the Day will bring it to light; and on the judgment day, fire will reveal what kind of work each builder has done. The fire will show if a person’s work has any value.”
