“Justifying faith is not a naked assent to the truths of the gospel.”
“The sanctified body is one whose hands are clean. The stain of dishonesty is not on them, the withering blight of ill-gotten gain has not blistered them, the mark of violence is not found upon them. They have been separated from every occupation that could displease God or injure a fellow-man.”
To start off with, I’d say that we as humans are neither able to justify nor to sanctify ourselves in order to make our way to God. Instead, both transforming periods of spiritual life are gifts from our Father through Jesus Christ. While the first one, justification, changes our whole thinking regarding God, ourselves, and others, and gives us the bedrock our spiritual house can be built upon, the second process that sanctifies our whole being enables us to change our behavior, too.
