The knowledge of good and evil we inherited from Adam is a dimension of our intellect so innate, so instinctual, so intuitive, so pervasive a way of responding to our everyday circumstances, it is virtually impossible to avoid.
Our propensity to rely on this understanding molds our demeanor and, once established, those tendencies can be difficult if not impossible to change even when we no longer want to live that way.
It shapes our outlook, acting as a filter for our perceptions, relationships, and experiences. It is an internal voice constantly reiterating events in our past or rehearsing future encounters so that we rarely exist in the present.
The apostle Paul called this knowledge his flesh—his fallen nature forcing him to serve the law of sin. Genesis states that in the beginning of their relationship, Adam and his wife were both naked but were not ashamed of their nakedness. When their eyes were opened, they became aware of the merits of their individual differences.
While those differences were there all along, they now compared their own uniqueness in light of their newly acquired understanding.
