Why do they have to be? Do you think everything our government does is moral, or for the good of the people? And ours is a democracy - not a theocracy, or a dictatorship like the governments of the past.
Nope. But everything the government does is based on morality and social norms of the time.
Not acknowledging thine iniquity (Jere 3:13) - Power by establishing lack of value in the people
Afraid to confess Jesus to the people (Jn 12:42) - Spread of empire
Not becoming as a little child before god (Mt 18:3) - Power through establishing incompetence in the people
Wearing the clothing of the opposite sex (Deut 22:5) - Fear and bigotry, really. I suppose you could debate this one, but on what grounds other than fear and bigotry?
Turning to false counsil/fables (2 Tim 4:4) - You can only believe in OUR fairytales (power)!
Not submitting to the king (all over the place) - Blatant political power.
Debating (Ro 1:29) - Heh. Just for the lolz. Though I suspect this had to do with not allowing the people the impression of self-empowerment
Not fearing god (all over the place) Control through fear
Robbing god by not giving 10% of your income, and offerings (Mal 3:8) - Obvious greed of the Church, and by proxy the government
Being an effeminate man (Cor 6:9) - Bigotry
Not being perfect (all over the place) - Impossible goal to inspire shame in the people, look to authority for guidance
A teacher being called a rabbi (Mt23:8) - Distaining religious competition (the bad guys)
Not believing (Rec 21:8) - Fiating its own rightness into existance for no reason
Wives not submitting to their husbands (Eph 5:22) - Continuation of oppression (you can argue morals, but it's no more arguable than the morality of slavery - they did it because they could and they liked the power)
And there is nothing here that I do not see that is based on morality or social norms of the time. Watch:
Not acknowledging thine iniquity (Jere 3:13) - It is bad to be judgmental and not acknowledge that. People will think less of you.
Afraid to confess Jesus to the people (Jn 12:42) - It is good to enourage others to have faith. Society is stronger if people believe (norm of the time... and a way to unite people).
Not becoming as a little child before god (Mt 18:3) - It is good to have awareness. People will respect you.
Wearing the clothing of the opposite sex (Deut 22:5) - It is bad to be a transvestite. This supports homosexuality which is bad... as it does nothing to increase the population (belief of the time).
Turning to false counsil/fables (2 Tim 4:4) - It is good and important to accept laws and rules. Society is stronger.
Not submitting to the king (all over the place) - It is good and the norm of the time to follow one's leader. Society is stronger.
Not fearing god (all over the place) It is bad and not the norm of the time to not accept God. This is an excellent example... as this has now changed.
Robbing god by not giving 10% of your income, and offerings (Mal 3:8) - It is a norm of the time to support the government. Interestingly enough, it is the norm of this time, too.
Being an effeminate man (Cor 6:9) - It is bad to be gay. Same reason as with transvestites.
Not being perfect (all over the place) - It is good to strive towards perfection. Not doing so makes you lazy.
A teacher being called a rabbi (Mt23:8) - This is nothing but the language of the time.
Not believing (Rec 21:8) - It is good to have faith. This allows one to not be weak (belief of the time).
Wives not submitting to their husbands (Eph 5:22) - Norm of the time was that women were lessers to men. Society is stronger when there is a hierarchy and a deliniation of positions.
You are abscribing some nefarious reason to each of these. All they are, are moral tenets that went along with the social norms of the time. And notice... as times have changed, so have those norms, as have laws.
