Not only those things, but now I think that all things are worth nothing compared with the greatness of knowing Christ Jesus my Lord. Because of Christ, I lost all those things {I thought were important}. And now I know that all those things are worthless trash. This allows me to have Christ.
It allows me to be in Christ. In Christ I am right with God, and this being right does not come from my following the law. It comes from God through faith. God uses my faith in Christ to make me right with him.
