Lust is "craving sexually what God has forbidden". Lust can also be defined as intemperate or irregular sexual desire, and is one of the Seven Deadly Sins. Often confused with love, it is purely physical attraction for an individual, that is sometimes uncontrollable and completely unreasonable.
Lust, in its most common expression, is the urge to initiate in sexual intercourse with another person. It may also manifest itself as the urge to view pornography, think sexual thoughts, or have unnatural sexual arousals, such as a homosexual thought. God's laws against lust are strictly meant to be obeyed throughout the Bible, for obedience justifies a believer by their faith, thus creating eternal salvation by their acceptance of the Sacrifice of Christ to save sinners from their sins.
According to evolutionist views, sexual desire evolved by natural selection as an instinct to increase the number of offspring - as those individuals more prone to lust would have more children than those less lustful, over time the prevalence of lustful traits would increase.

According to Christian views, lust is a consequence of the separation of a person from God as a result of sin, causing them to fall short of His standard. Some churches attribute lust to direct satanic involvement, or advocate various means by which unwanted lust may be controlled.
The word 'lust' can also be used more generally to describe any intemperate or excessive desire, for example, lust for power, lust for fame, or personal glory, is highly synonymous with the personality trait of narcissism.
