1 John 1:8
[SUP]8 [/SUP] If we say that we have no sin, we deceive ourselves, and the truth is not in us.
Romans 7:24-25
[SUP]24 [/SUP] O wretched man that I am! Who will deliver me from this body of death?
[SUP]25 [/SUP] I thank God--through Jesus Christ our Lord! So then, with the mind I myself serve the law of God, but with the flesh the law of sin.
Its our flesh that sins all the time, not necessary our Lusts. You can still not lust and sin. Lust is just only one kind of sin. There are many others.
Galatians 5:19-21
[SUP]19 [/SUP] Now the works of the flesh are evident, which are: adultery, fornication, uncleanness, lewdness,
[SUP]20 [/SUP] idolatry, sorcery, hatred, contentions, jealousies, outbursts of wrath, selfish ambitions, dissensions, heresies,
[SUP]21 [/SUP] envy, murders, drunkenness, revelries, and the like; of which I tell you beforehand, just as I also told you in time past, that those who practice such things will not inherit the kingdom of God.
Hatred is not a Lust but yet its a sin. Being jealous is not a lust but its a sin. There are many sins not based on Lust alone.
