The mind is that faculty of the human personality that thinks and discerns. The duty of the mind in relation to sin is to discern its evil nature and its dangers to the soul...One of the functions of the mind is to serve as the surveillance system for the soul. So, for sin to ply its trade on us, it first has to neutralize the mind. And it does this is several ways:
Sinful desire exploits our natural weaknesses and limitations.
Sinful desires trick the mind into thinking that sinning is not big deal.
Sinful desire leads us to abuse God's grace.
Sin also assaults the mind by disassembling the components of theological truths from one another. It tries to separate justification (right standing before God) from progressive sanctification (increasing holiness in our actual lives). It seeks to highlight our pardon from guilt, yet obscure our freedom from slavery. It wants the removal of sin's curse, without the cleansing of sin's stain.
