I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God who loved me, and gave himself for me.
Galatians 2:20 (KJV)
Through our union with Christ our old self has been crucified with Him, and we have been given a new self which is created after His image and likeness. As we deliberately remember each day who we have been made to be in Him, we are no longer held in bondage to the things of the flesh. Through faith in Jesus we partake of His nature, thereby becoming instruments through which His glory may be made manifest in the earth.
