a spiritual person is dying to the old man and living in the new which means you must be a spirit/personality in order to decide if doing such a thing is good or wrong for you. remember that in sin we are dead but if we are given life by God then we are finally becoming what we really are.
the old man is regulated to death with rules due to the nature of sin and it's ability to corrupt every good thing and twist it into some kind of evil.
the spiritual man sees the law from the liberty of spirit and understands some kind of useful wisdom that it symbolically expresses. the one who is spiritual will do what they do because they feel it is good and nice and all they do will be good because they have communion with their Father.... unless they have been lead astray by some sin.
to be so concerned about such a minor thing could be a sign that you are under the bondage of the law and bondage of the fear of punishment for doing something evil. your concern about such a thing might also show that you deeply care what Gods will is for you.
we Christians who seek God are in a process of dying to the old and being born again in God.
Col 3:5-17 (YLT)
Put to death, then, your members that are upon the earth--whoredom, uncleanness, passion, evil desire, and the covetousness, which is idolatry-- because of which things cometh the anger of God upon the sons of the disobedience, in which also ye--ye did walk once, when ye lived in them; but now put off, even ye, the whole--anger, wrath, malice, evil-speaking, filthy talking--out of your mouth. Lie not one to another, having put off the old man with his practices, and having put on the new, which is renewed in regard to knowledge, after the image of Him who did create him; where there is not Greek and Jew, circumcision and uncircumcision, foreigner, Scythian, servant, freeman--but the all and in all--Christ. Put on, therefore, as choice ones of God, holy and beloved, bowels of mercies, kindness, humble-mindedness, meekness, long-suffering, forbearing one another, and forgiving each other, if any one with any one may have a quarrel, as also the Christ did forgive you--so also ye; and above all these things, have love, which is a bond of the perfection, and let the peace of God rule in your hearts, to which also ye were called in one body, and become thankful. Let the word of Christ dwell in you richly, in all wisdom, teaching and admonishing each other, in psalms, and hymns, and spiritual songs, in grace singing in your hearts to the Lord; and all, whatever ye may do in word or in work, do all things in the name of the Lord Jesus--giving thanks to the God and Father, through him.
the "name" of Lord Jesus would be in his way of being by you in him and he in you in spiritual communion, not merely some legalistic confession or law of everything you do with the spoken words "in the name of Jesus I put/take my earrings on/off".
if you can't stop from being a harlot by wearing earrings I suggest you humble yourself and take them off. if you can be a good person with them on then where is the sin in wearing earrings? what if you become so anal that you fall away from God due to you quenching the Spirit of God? don't let that happen!
1Thess 5:16-19 (YLT)
always rejoice ye; continually pray ye; in every thing give thanks, for this is the will of God in Christ Jesus in regard to you. The Spirit quench not;
Matt 23:23-31 (YLT)
`Woe to you, Scribes and Pharisees, hypocrites! because ye give tithe of the mint, and the dill, and the cumin, and did neglect the weightier things of the Law--the judgment, and the kindness, and the faith; these it behoved you to do, and those not to neglect. `Blind guides! who are straining out the gnat, and the camel are swallowing. `Woe to you, Scribes and Pharisees, hypocrites! because ye make clean the outside of the cup and the plate, and within they are full of rapine and incontinence. `Blind Pharisee! cleanse first the inside of the cup and the plate, that the outside of them also may become clean. `Woe to you, Scribes and Pharisees, hypocrites! because ye are like to whitewashed sepulchres, which outwardly indeed do appear beautiful, and within are full of bones of dead men, and of all uncleanness; so also ye outwardly indeed do appear to men righteous, and within ye are full of hypocrisy and lawlessness. `Woe to you, Scribes and Pharisees, hypocrites! because ye build the sepulchres of the prophets, and adorn the tombs of the righteous, and say, If we had been in the days of our fathers, we would not have been partakers with them in the blood of the prophets. So that ye testify to yourselves, that ye are sons of them who did murder the prophets;
to not neglect would mean to have and live in the Holy Spirit rather than the letter of the law.
2Cor 3:6-18 (YLT)
who also made us sufficient to be ministrants of a new covenant, not of letter, but of spirit; for the letter doth kill, and the spirit doth make alive. and if the ministration of the death, in letters, engraved in stones, came in glory, so that the sons of Israel were not able to look stedfastly to the face of Moses, because of the glory of his face--which was being made useless, how shall the ministration of the Spirit not be more in glory? for if the ministration of the condemnation is glory, much more doth the ministration of the righteousness abound in glory; for also even that which hath been glorious, hath not been glorious--in this respect, because of the superior glory; for if that which is being made useless is through glory, much more that which is remaining is in glory. Having, then, such hope, we use much freedom of speech, and are not as Moses, who was putting a vail upon his own face, for the sons of Israel not stedfastly to look to the end of that which is being made useless, but their minds were hardened, for unto this day the same vail at the reading of the Old Covenant doth remain unwithdrawn--which in Christ is being made useless-- but till to-day, when Moses is read, a vail upon their heart doth lie, and whenever they may turn unto the Lord, the vail is taken away. And the Lord is the Spirit; and where the Spirit of the Lord is , there is liberty; and we all, with unvailed face, the glory of the Lord beholding in a mirror, to the same image are being transformed, from glory to glory, even as by the Spirit of the Lord.
