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.
Therefore, I will always be ready to remind you of these things, even though you already know them and are established in the truth which is held firmly in your grasp. I think it right, as long as I am in this earthly tent, to inspire you by reminding you, knowing that the laying aside of this earthly tent of mine is imminent, as our Lord Jesus Christ has made clear to me. Moreover, I will diligently endeavor [to see to it] that even after my departure you will be able, at all times, to call these things to mind.
