And above all things be earnest in your love among yourselves, for love covers a multitude of sins.
because love covers a large number of sins -- Peter draws on Proverbs 10:12 to affirm the power of Christian love; it can result in forgiveness and reconciliation when people have been harmed or wronged (James 5:20). In this way, love overcomes sin. Early Christianity regarded love as the foundational ethic for the community of believers (John 13:34-35; 1 Corinthians 13:1-13; Galatians 5:13-14; Colossians 3:14). - FSB
