⁵ For this very reason, make every effort to supplement your faith ^(A)with virtue,^[a] and virtue ^(B)with knowledge, ⁶ and knowledge with self-control, and self-control ^(C)with steadfastness, and steadfastness with godliness, ⁷ and godliness ^(D)with brotherly affection, and brotherly affection ^(E)with love. ⁸ For if these qualities^[b] are yours and are increasing, they keep you from being ineffective or ^(F)unfruitful in the knowledge of our Lord Jesus Christ. ⁹ For whoever lacks these qualities is so nearsighted that he ^(G)is blind, having forgotten that he was ^(H)cleansed from his former sins. ¹⁰ Therefore, brothers,^[c] be all the more diligent to confirm your calling and ^(I)election, for if you practice these qualities ^(J)you will never fall.
