3:12-15 Some of the things that people build on the foundation of Christ will endure; other things will burn up in the fire of judgment (cp. Mal 4:1). On judgment day, the work of each builder who instructs the church will be assessed (cp. Jas 3:1; see also Rom 14:10-12; 2 Cor 5:10). Those whose teachings are faithful and true will receive a reward; the others will suffer great loss, not of their salvation but of their reward. They themselves will be saved, but just barely, like someone pulled to safety through a wall of flames (cp. Amos 4:11; Zech 3:2; Jude 1:23).
