(rabbit trail: can sins be considered in stages - are there really lesser sins? Perhaps of lesser strength or impact on the aggressor and/or agressee but are there any unimportant sins? Isn't a sin... a sin?)
Perhaps this is related to:
"Do not love the world [of sin that opposes God and His precepts], nor the things that are in the world. If anyone loves the world, the love of the Father is not in him. For all that is in the world—the lust and sensual craving of the flesh and the lust and longing of the eyes and the boastful pride of life [pretentious confidence in one’s resources or in the stability of earthly things]—these do not come from the Father, but are from the world. 17 The world is passing away, and with it its lusts [the shameful pursuits and ungodly longings]; but the one who does the will of God and carries out His purposes lives forever." [1 John 2: 15-17]
When you look at the sin of coveting - isn't all of that related to those 3 - flesh, eyes, life? And now look at the behavior that is often associated with following those desires. When someone covets (over desires) how do they react - are they consumed by their own desires? Sometimes. But it's the behavior that is also at issue - time is wasted by thinking on it. But it can also lead to worse behavior. You know if you are 'over desiring' or not and what it leads to. Do you want this for yourself? Remember... this is self analysis. You also have the power to change and no longer have wrong desires controlling you. Remember what James says:
"What leads to [the unending] quarrels and conflicts among you? Do they not come from your [hedonistic] desires that wage war in your [bodily] members [fighting for control over you]? You are jealous and covet [what others have] and [your lust goes unfulfilled; so you murder. You are envious and cannot obtain [the object of your envy]; so you fight and battle. You do not have because you do not ask [it of God]. You ask [God for something] and do not receive it, [hedonistic] desires." [James 2: 1-3]
Reread verse 2. Doesn't this speak to coveting? The reasons, answers to why you don't have what you think you want/need is found in verse 3. Do you honestly know WHY you want what you think you want? Is it a 'keeping up with the Joneses'? Do you pray for those things to the Lord that really aren't needs so you don't receive?
"And when you pray, do not use meaningless repetition as the Gentiles do, for they think they will be heard because of their many words. So do not be like them [praying as they do]; for your Father knows what you need before you ask Him." [Matthew 8:7-8]
He knows and He is the source of every good gift (James 1:17) but He does expect us to ask (Matthew 7: 7-8) just not ask incorrectly.
