We need to consider what sin is. Back in the 1930's going to the cinema was a sin, dancing or using make-up a sin. Sin changes according to the time.
The Greek word hermatia translated as sin, means to miss the mark. Why do we miss the mark, because satan blinds our minds. When we are born again we receive the mind of Christ and see the target clearly.
According to 1 John 3:8 "who does sin is of the devil."
In verse 9 we are told, "Everyone born of God does no sin, because His Seed (the Lord Jesus) abides in him: and he cannot sin, because he is born of God." The word cannot in Greek is ou dunatai, basically no power.
Sin is a nature not an action, we have the nature of God. According to 2 Corr. 5:17 "If that any in Christ, he is a new (kainos new never existing before, totally different) creature: the old passed away; lo they are become new. Kainos again. So we become a new creature filled with all the fullness of God, but the "church" tells us we can sin. You drink alcohol, you smoke etc. The "church" labels actions it doesn't agree with as sin!
According to Romans 12:2 "Be transformed (metamorphosized) by the renewing (Kainos again, we have to think like God) of your mind." So it is imperative that we re-program our minds to think God's way. The way to do this is study the Church Epistles, the letter written to the Spirit filled churches.
Does this mean we can do whatever we like? No! We are under the law of love, we can not do anything which would harm another, including ourself. If it brings Love, Joy, Peace then go for it. Remember satan will bombard your mind, but take every thought captive to the obedience of Christ.
Follow the words of that great theologian, Jiminy Cricket, "Let your conscience be your guide." The Holy Spirit will give a check, to your spirit, if it is wrong!
[Greek has two word for new, neos and kainos. William Barclay in his New Testament give an illustration to explain the difference. The millionth pencil produced on a production line is just as neos as the others. But if the millionth produced is a pen then it is kainos, totally different.]
