In the Bible, human good is contrasted with divine good which is the work produced by the Spirit of God in the life of a believer. The Sin Nature also has an area of weakness which manifests in the the production of all personal sin. The Sin Nature has patterns of desires, the basic motivators of all the activities of human life. The basic drives include the desire for power, approbation, ego satisfaction, sexual satisfaction, material satisfaction, and so forth. The Sin Nature has a system of trends, or inclinations, which vary among individuals.
Some people have an inclination toward immorality or lasciviousness.
Others have trends toward morality or asceticism. Either trend is a product of Sin Nature activity. This is because the trends of the sin nature are derived from the individual lust pattern. There are certain areas in which we lust, and other areas where we do not, and these differ between individuals. The trends of the sin nature are classified in two overreaching categories, legalism and lasciviousness.
