I'm only a few chapters deep into Holiness but am finding myself constantly struck and convicted and moved and blown away by what I'm reading. These paragraphs are from his chapter on sin, conveniently titled, "Sin."
The plain truth is that a right understanding of sin lies at the root of all saving Christianity. Without it such doctrines as justification, conversion, sanctification, are "words and names" which convey no meaning to the mind. The first thing, therefore, that God does when He makes anyone a new creature in Christ is to send light into his heart and show him that he is a guilty sinner.
The material creation in Genesis began with "light," and so also does the spiritual creation. God "shines into our hearts" by the work of the Holy Spirit and then spiritual life begins (2 Cor. 4:6). Dim or indistinct views of sin are the origin of most of the errors, heresies and false doctrines of the present day. If a man does not realize the dangerous nature of his soul's disease, you cannot wonder if he is content with false or imperfect remedies.
I believe that one of the chief wants of the contemporary church has been, and is, clearer, fuller teaching about sin.
