Here's how i look at holiness and the law. We all know that just thinking something makes us guilty of it, but Gods gives us his grace, we cannot be perfected in the flesh only the spirit, but the flesh wars against the spirit so we must forsake works of the flesh if we want to walk in the spirit and bear Good fruit. We must choose to limit what our eyes see if we want to limit what we think about. We will never be free of evil thoughts 100% maybe, but if we want to think good things we must not look at bad things. Even though we are forgiven for every sin we confess to God, we can't bear good fruit if our minds our corrupted by works of the flesh. Its not necessarily that we sinned in those evil thoughts, even though we did, its mostly about bearing good fruit that is pleasing to God and those thoughts war against that good fruit. Its most likely impossible to always have good thoughts because things enter our mind that we don't want there, even so we must choose to cast down these evil thoughts and we can only do it through effort on our part through prayer and censoring what we see and hear to only good things. Only then will we be able to walk in the spirit and bear good fruit for God. Sin wars against the Spirit and if we choose to indulge in sinful thoughts we will bear bad fruit. But if we cast those thoughts down by not indulging in them and also limit what we see to only good things, over time we will begin to think more good and less bad, and in the process we will begin to bear good fruit of the spirit. Sinful thoughts are violence, lust, the love of money and power, hate, revenge, and anything that glorifies sin. TV is just plain evil. We must sensor what we watch, this doesn't mean we can't watch an action flick every once in a while necessarily, but we need to identify what bad fruit we bear and stay away from those things as much as possible. Children get brainwashed by TV and music so its no wonder they are so disrespectful and sinful in todays world.
So the law is not bad, its designed to help us. If we think something is sin then for us its sin and we shouldn't do it because it makes us enemies to God. However it goes deeper than that, we cant get close to God by sinning, and also if we use the law to think we are righteous then we abuse the law because its designed so that we can get closer to God and love Him and each other. I think maybe its about loving God through obedience, loving each other and bearing Good fruit of the Spirit..
