Greetings, 

It's not about words at all. What is God, or Christ,  what is the Law, or what is natural? 

If you were to go to a dictionary or a book for a definition of any word, guess what you'll find? You guessed it, more words! You can't get more circular in reasoning than that! As one word does not interpret another so one flesh cannot explain another. Only the life that made them all knows them all. The same life in which we share. The definition of anything is us. 

A superstitious mind abides in those who know themselves according to outward-based imagination, whether they call themselves Christian or not; there is no difference. The perceptions blind them all as they rationalize the numerous inconsistencies they become aware of as even real life itself rejects their expectations. 'We are Christian',  or ' We obey God' or 'Christ said this..'. ​Behind all the verbiage stands the perception, which is either appearance-based or not. Whole isolated spheres of flesh-based mental interactions are made up. But at the same time these structures become the just condemnation of torment and bondage for those who would to live in them. After all, they work hard for it and so their due payment of intense anxiety and unspeakable fear is well deserved! They imagine that the reality of justice can somehow be broken, whether in the natural world or outside of it. Hence they speak of in-justice, as if they knew what justice is in the first place. Similarly, they speak of disobeying the Law, as if they knew what the Law is. Even in this their own imagination will bring the justice of ruin to them, and it does so daily!

The living reality of God is utterly disgusted with the mind of the appearance, the mind of those perceptions that imagine that hope and what is right lie somewhere in the behavior. It is in him that we also became the fundamental reality of justice in view of which the mind of the world is seen to be under the condemnation of finality. For us, there's no such thing as disobedience. The living evidence of being in the world of the life of Christ is the same unutterable disgust that we inherited and that we share with him towards the fleshly mind.  Those that  so readily speak of disobedience are condemned by their own mind's appearance-based perceptions of regulations.

I've been in situations such as the one you address. And all I've heard has been the attempt of some to preserve those their own failing perceptions. These people cannot properly assess and address behavior, daily life,  or anything for that matter, because they are not at all concerned with the real things, but only with their erroneous perceptions of them.

'But, on the other hand, in what my friend said I felt there was a separation between the believer and Christ.'

I don't think it's that kinds of separation that he is describing since apart from wording he is not at all speaking of a believer or of Christ. The foul stench of corruption comes rather from a mind of death dealing intentions that is itself being separate from true life. It is at best a description of one's own awareness of transgression.

'..because they will become more obedient to God's Laws. But, they will not need to be coerced by others from what the Bible says to do, or feel compelled by a rule to obey God's Laws. But the obedience is natural not a chore. It's their delight to obey God's Laws.'

Obedience can only be graded within the mind of error. The motions of our obedience cannot be measured or uttered, because they are the life of God. While being sure to add the verbiage about the un-necessary coercion, these competent people nevertheless attempt to impart a guilt-ridden and fear-full mind as they play out its self-righteous schemes. More than anyone else, they deceive themselves. I have done it also through the same pattern of speech, seeking to bind others to my guilt.
