2 Peter 1:5-11

For this very reason, applying your diligence [to the divine promises], make every effort in [exercising] your faith to develop moral excellence, and in moral excellence, knowledge (insight, understanding), and in your knowledge, self-control, and in your self-control, steadfastness, and in your steadfastness, godliness, and in your godliness, brotherly affection, and in your brotherly affection, [develop Christian] love [that is, learn to unselfishly seek the best for others and to do things for their benefit]. 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. Therefore, believers, be all the more diligent to make certain about His calling and choosing you [be sure that your behavior reflects and confirms your relationship with God]; for by doing these things [actively developing these virtues], you will never stumble [in your spiritual growth and will live a life that leads others away from sin]; for in this way entry into the eternal kingdom of our Lord and Savior Jesus Christ will be abundantly provided to you.
