Many people are using the wrong definition for the word "power" in I Corinthians!
Mat 22:29 Jesus answered and said unto them, Ye do err, not knowing the Scriptures, nor the
power 1411 of God.
G1411
δύναμις
dunamis
doo'-nam-is
From G1410; force (literally or figuratively); specifically miraculous power (usually by implication a miracle itself): - ability, abundance, meaning, might (-ily, -y, -y deed), (worker of) miracle (-s), power, strength, violence, mighty (wonderful) work.
1Co 11:10 For this cause ought the woman to have
power1849 on her head because of the angels.
G1849
ἐξουσία
exousia
ex-oo-see'-ah
From G1832 (in the sense of ability); privilege, that is, (subjectively) force, capacity, competency, freedom, or (objectively) mastery (concretely magistrate, superhuman, potentate, token of control), delegated influence: - authority, jurisdiction, liberty, power, right, strength.
Having understood this, I see that the "power in the hair" is not miraculous, but being a privilege, a freedom and a right.
