ISB ~ 1 Peter 1 v6

suffer various trials:Endurance of suffering and persecution is frequently mentioned in the letter (2:1922; 4:1, 12-19; 5:9-10). It is here compared to a smelting process that removes alloys and impurities from precious metals such as gold (1:7; Job 23:10; Sir 2:4-5). Suffering, Peter says, is the fire that refines our faith and makes us more like Christ, whose own endurance of torment was an expression of filial obedience to the Father (1 Pet 2:21; Phil 2:8; Heb 5:8) (CCC 618, 1031).

• The saints, perceiving the benefits of divine fire, did not shrink from trials or become discouraged by them. Instead of suffering injury, they were improved by what they endured, gleaming like gold refined in fire (St. Athanasius, Festal Letters 10).
