These are two of my more favorite verses. I have several others, but these two pretty much sums up my position in Christ Jesus.
Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new. (2 Cor. 5:17).
I have been crucified with Christ; 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 for me. (Gal. 2:20)
