But for this very reason--adding, on your part, all earnestness-- along with your faith, manifest also a noble character: along with a noble character, knowledge;

along with knowledge, self-control; along with self-control, power of endurance;

γνώσει gnōsei “knowledge”

But be always growing in the grace and knowledge of our Lord and Saviour Jesus Christ. To Him be all glory, both now and to the day of Eternity!
