2 Peter 1:5-9 (ESV)

⁵ For this very reason, make every effort to supplement your faith with virtue, and virtue with knowledge, ⁶ and knowledge with self-control, and self-control with steadfastness, and steadfastness with godliness, ⁷ and godliness with brotherly affection, and brotherly affection with love. ⁸ For if these qualities are yours and are increasing, they keep you from being ineffective or unfruitful in the knowledge of our Lord Jesus Christ. ⁹ For whoever lacks these qualities is so nearsighted that he is blind, having forgotten that he was cleansed from his former sins.
