Your interpretation of this verse implies that only men are the people of God and that children and women are not part of God's people.
No, "my people" refer to all who claim God and whom God claim's are "my people." - The people of God
America claims to be the people of God. It is on our money "In God we Trust" and nearly 85% claim to believe in God.
The same is true of America. Those that rule the nations have destroyed discipline in the classrooms of American's educational system so that children become their oppressors. Women have rejected the role of raising children and tending to their faimlies but have usurped the role of men trying to rule over them in the home, the work place and in government.
Those that lead our country are guilty of the same thing Isaiah charges Israel with.
God has established a Biblical order (1 Cor. 11:3) among mankind as there is a Biblical order within the very Godhead. Go study the metaphorical use of the term "head" in 1 Cor. 11:3 and ask yourself is the Biblical order in the Godhead something temporary or cultural???????????
