As above, so below; As below, so above.
Keep in mind that GOD = LORD = earthly government ordained by God almighty, thus the Name upon the BC is much like a "sacred writing": the LORD'S NAME.
So, to change the name, is akin to DEFILING the name of GOD and taking the LORD'S Name in VAIN by thinking the Name serves to identify one instead of just identifying one's interests which is also an act of IDOLATRY. This act also rejects the Government ordained by ORDINANCE of God almighty (see Romans 13)
by treating the Gift of GOD as UNCLEAN (see Romans 1:18-32 and Romans 14:14)
Thus, changing the name is PROFANE
Profane (standard Webster's dictionary definition)
1. (a.) Not sacred or holy; not possessing peculiar sanctity; unconsecrated; hence, relating to matters other than sacred; secular; -- opposed to sacred, religious, or inspired; as, a profane place.
2. (a.) Unclean; impure; polluted; unholy.
3. (a.) Treating sacred things with contempt, disrespect, irreverence, or undue familiarity; irreverent; impious.
4. (a.) Irreverent in language; taking the name of God in vain; given to swearing; blasphemous; as, a profane person, word, oath, or tongue.
5. (v.) To violate, as anything sacred; to treat with abuse, irreverence, obloquy, or contempt; to desecrate; to pollute; as, to profane the name of God; to profane the Scriptures, or the ordinance of God.
6. (v.) To put to a wrong or unworthy use; to make a base employment of; to debase; to abuse; to defile.
The Name Change would serve as the Mark of Cain because if someone did something to harm one, the damage would come back sevenfold because of the protections God almighty COMMANDED (see Genesis 4:11-16)
. So, the Name Change will serve as a "form of protection", however if one should attempt to "farm the Earth", the Earth shall produce no fruit for one now lives a PROFANE-LIFE: Living in SIN by free will choice and consent unable to interact with the LORD, thus one's ability to engage in commerce would be non-existent and one would have to resort to being either a "Vampire", doing as Cain did, or Accept the mark of the Beast.
Now, the NAMES you refer to below such as Madonna, Prince, Ke$ha, etc... are actually IDOLS created by another in order to receive the worship of heathens; farming SIN for their own SELFISH-GLORY, thus SATANIC.
Terms of endearment used by friends and family, are just that. I have many names I use for buddies and others. But those are not the names they were "baptized" under, just terms of endearment, showing Love with a personal touch.
Again, this is about the DESIGN and OPERATION of "the system", not about one's personal beliefs nor affairs.
We are called to be architects of the future, not its victims;
Resistance is futile.
If you think you can, you are correct.
If you think you can't, you are correct.
