My Righteousness

Philippians 3:7-11

7 But whatever things were gain to me, those things I have counted as loss for the sake of Christ. 8 More than that, I count all things to be loss in view of the surpassing value of knowing Christ Jesus my Lord, for whom I have suffered the loss of all things, and count them but rubbish so that I may gain Christ, 9 and may be found in Him, not having a righteousness of my own derived from the Law, but that which is through faith in Christ, the righteousness which comes from God on the basis of faith, 10 that I may know Him and the power of His resurrection and the fellowship of His sufferings, being conformed to His death; 11 in order that I may attain to the resurrection from the dead.
NASU

Action: Where does my righteousness come from? How do I grow my righteousness?
