Here I go again with yet another multi-part series. As I begin I have not a clue as to how many I’ll write, but what I do sense is that each commentary (every day) needs to have a couple of nuggets of truth that can be pondered for awhile, eating slowly and digesting the spiritual food; rather than gorging ourselves on one meal and then feeling sick and bloated. In the Old Testament, we have three major themes: the wilderness journey, the exile, and the temple worship. The church has camped way too long and too severely in the temple concepts which basically speak of sin and sin management. It’s time to move on to the GOOD NEWS!
SIN is basically a church-religious word that’s lost it’s meaning and appeal to the general populace.
There is no way that we can do away with the word, so we need to at least come to a general consensus as to what it really means and not what the church has made it out to be. Most people associate sin with sex. In fact, many think the two to be the same words. SIN is SEX and SEX is SIN. You can thank St. Augustine for that.
Sex is dirty!
NOT! 
When you hear the phrase, “they are living in sin“, it means they are having sex while not married, sex with someone else other than whom they are married, sex not in the missionary position only, or sex for pleasure, and not just for procreation. Give me a holy break here. Or secondarily, sin means that someone has broken some “moral code” that they, the writers feel is moral- not necessarily what God thinks.
You do know that man has a million more moral laws than God! Right?
Getting past all of man’s prejudices and opinions, sin is about the relationship between God and man. Note that I highlighted the word relationship. SIN is specifically a religious concept. And, it has far more to do with how and how much time we spend with God than anything else. This is the key and the direction I intend to go in this series.
I am not advocating that one should sin (far from it); however, I would submit that there are many, many people who sin but have a great relationship with God and that pleases God (not the sin) because that LOVE covers a multitude of sins. On the other side of the coin, there are many who sin little (in public) and appear righteous, before the law, but have no real relationship with God. They know facts about God, but they know nada about God!
Need I say more?
Ah, but, I will tomorrow, and the day after that! 
I have come to understand what sin is (love your example: sex is not sin, just as drinking wine or eating non-existant “unclean food” doesn’t equal sin, shopping isn’t sining). But any of these things in excess can become an idol, which is a sin. How do we deal with the conviction from the Holy Spirit and repentance?
