For if you posses these qualities in increasing measure, they will keep you from being ineffective and unproductive in your knowledge of our Lord Jesus Christ.
But if anyone does not have them, he is nearsighted and blind,and has forgotten that he has been cleansed from his past sings. Therefore, my brothers, be all the more eager to make your calling and election sure. For if you do these things, you will never fall and you will receive a rich welcome into the eternal kingdom of our Lord and Savior Jesus Christ.
2 Peter 1:8-11
I have to memorize this! AHH, but so much truth in it!
