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.
I don't mean that I am already exactly like God wants me to be. I have not yet reached that goal. But I continue trying to reach that goal and to make it mine. Christ wants me to do that. That is the reason Christ made me his.
Brothers and sisters, I know that I have not yet reached that goal. But there is one thing I always do: I forget the things that are past. I try as hard as I can to reach the goal that is before me.
All of us who have grown spiritually to be mature (perfect) should think this way too. And if there is any of these things you don't agree with, God will make it clear to you.
