It was Paul who said...
"What is more, I consider everything a loss compared to the
surpassing greatness of knowing Christ Jesus my Lord,
for whose sake I have lost all things. I consider them rubbish,
that I may gain Christ and be found in Him,
not having a righteousness of my own that comes from the law,
but that which is through faith in Christ–
the righteousness that comes from God and is by faith." Phil 3:8-9
