The greatest truth we can ever be told is that our old self has gone. I can deal with the body of sin only as I realize that my old self has gone, and I have a new self. This is the most striking and amazing truth.
~ D. Martyn Lloyd-Jones
If you are a Christian, it’s a serious misunderstanding to think of yourself as having both an old and new nature. We do not have a dual personality! Assuming the dual nature of the believer could easily lead one to excuse all kinds of sins by blaming them on the old nature. The popular theological concept of the old man and the new man fighting each other is not biblically accurate.
~ John MacArthur
We live as though our ‘old man’ is still alive, even though we are dead to him. He has no right to be in our conscious thinking. We serve a new Master who has walked us across the threshold, who has awakened us to new life, new love, to a new relationship and to an entirely different future.
