A.B. Simpson emphasizes the necessity of dying to self through the cross of Christ, highlighting that true transformation cannot be achieved through self-effort but through surrendering to Jesus. He points out that many in the church struggle with their old selves, attempting to overcome their sins without fully embracing the death that Christ offers. By placing ourselves at Jesus' feet and allowing His death to be applied to our nature, we can find rest and accomplishment. Simpson encourages believers to consider their old selves as dead and to depend on Christ for their new life, much like a newborn relies on its mother.

This definite, absolute and final putting off of ourselves in an act of death is something we cannot do ourselves. It is not self-mortifying, but it is dying with Christ. Nothing can do it but the cross of Christ and the Spirit of God. The church is full of half-dead people who have been trying to slay themselves for years and have not had the courage to strike the fatal blow. Yet if they would just put themselves at Jesus' feet and let Him do it, there would be accomplishment and rest. On the cross He provided for our death as well as our life, and our part is just to let His death be applied to our nature as it has been to our old sins. When we have done this we must leave it all with Him, think no more about it and count it dead. Recognizing it as no longer ourselves, but another, we must refuse to obey it, or fear it, to be identified with it, or even try to cleanse it. We must consider it utterly in His hands-and dead to us forever-and depend on Him for every breath of our new life as a newborn baby depends upon the life of its mother.
