I Now Live

Galatians 2:20 NASB
20 I have been crucified with Christ; and it is no longer I who live, but Christ lives in me; and the life which I now live in the flesh I live by faith in the Son of God, who loved me and gave Himself up for me.
Paul speaks of a changed and new life.  The resurrection of Jesus allows us to follow after Him into life.  This is what it means that we must bear our own cross.  We have to give to Him what He gave to us.  He did not object to giving it all that we might have everything.  He could see the glory set before Him: ours and His for the glory of God.
Our person is not lost in this transaction.  On the contrary, we find we are merely the seed of who we will become.
