2 Peter 1:6-8

6 and to your knowledge, add self-control; and to your self-control, add the ability to hold on; and to your ability to hold on, add service for God;

7 and to your service for God, add kindness for your brothers and sisters in Christ; and to this kindness, add love.

8 If all these things are in you and are growing, they will help you never to be useless. They will help your knowledge of our Lord Jesus Christ make your lives better.
