2 Peter 1:9-11

9 For he who lacks these things is blind, seeing only what is near, having forgotten the cleansing from his old sins.  10 Therefore, brothers, be more diligent to make your calling and election sure. For if you do these things, you will never stumble.  11 For thus will be richly supplied to you the entrance into the eternal Kingdom of our Lord and Savior, Jesus Christ.
