All the medieval 'seven deadly sins' could be categorized as a facet of lust. Satan's pride was motivated by lust for power; all sinful things on the earth emerge from lust and pride. Lust could be described as evil or inordinate desire. God designed us to have proper desires, just as His desires are always proper. God has a desire for a family; Jesus Christ experienced the same desires as we do. Evil desires consist of lust for things contrary to God's law, such as fornication, uncleanliness, covetousness, and idolatry. God never tempts anyone, but we are tempted by our own evil desires. Trials are pressures to test us; temptations are pressures to cause us to sin. Our own evil desires hook us and drag us where we really do not want to go; we are seduced into sin. Evil desire led to man's first sin; the tree of the knowledge of good and evil was pleasing to the eyes and contained a (false) promise to make wise. Eating of this tree was the first act of lust resulting in sin and ultimate death. If evil desires are allowed to gestate instead of becoming aborted, sin will result. All sinful acts begin in the mind as desire, including the acts of murder, lying, adultery, and idolatry. As evil desire begins in the mind, overcoming also begins in the mind. We are admonished to flee fornication—not to stick around and contemplate it. We may have to physically remove ourselves from locations or certain acquaintances. When we drive out an evil thought, we must replace it with a godly thought; if we put good thoughts in, it will lead to good thoughts out. To guard against evil thoughts, we need to cultivate the habit of praying continually, guarding against or displacing all evil desire, winning the battle between the flesh and spirit.
