2 Peter 1:8-9

2 Peter 1:8-9 AMP

For as these qualities are yours and are increasing [in you as you grow toward spiritual maturity], they will keep you from being useless and unproductive in regard to the true knowledge and greater understanding of our Lord Jesus Christ. For whoever lacks these qualities is blind—shortsighted [closing his spiritual eyes to the truth], having become oblivious to the fact that he was cleansed from his old sins.
