2 Peter 1:8-11 New American Standard Bible (NASB)
8 For if these qualities are yours and are increasing, they do not make you useless nor unproductive in the true knowledge of our Lord Jesus Christ. 9 For the one who lacks these qualities is blind or short-sighted, having forgotten his purification from his former sins. 10 Therefore, brothers and sisters, be all the more diligent to make certain about His calling and choice of you; for as long as you practice these things, you will never stumble; 11 for in this way the entrance into the eternal kingdom of our Lord and Savior Jesus Christ will be abundantly supplied to you.
2 Peter 1:8-11 New International Version (NIV)
8 For if you possess these qualities in increasing measure, they will keep you from being ineffective and unproductive in your knowledge of our Lord Jesus Christ. 9 But whoever does not have them is nearsighted and blind, forgetting that they have been cleansed from their past sins.
10 Therefore, my brothers and sisters,[a] make every effort to confirm your calling and election. For if you do these things, you will never stumble, 11 and you will receive a rich welcome into the eternal kingdom of our Lord and Savior Jesus Christ.
