1 Corinthians 3:14 - Ellicott's Commentary On The Whole Bible

This is the general application to Christian teachers of what has gone before. Those who have built well shall have their reward in their work having survived the trial of the fire; those who have built otherwise shall lose everything — their work, which should have remained as their reward, will perish in the fire — and they themselves will be as men who only make good their escape by rushing through a conflagration, leaving all that was theirs to be destroyed. (See Mark 9:49.)
