Philippians 3:7-9

But whatever was gain to me I count as loss for the sake of Christ. More than that, I count all things as loss compared to the surpassing excellence of knowing Christ Jesus my Lord, for whom I have lost all things. I consider them rubbish, that I may gain Christ and be found in Him, not having my own righteousness from the law, but that which is through faith in Christ, the righteousness from God on the basis of faith.
