It says somewhere in the bible -
“If you love [God] you will obey [His] commandments”
Commandment #4 - Honor your mother and father.
For a child under 18 or whatever the age of ‘emancipation’ is in their particular country, this commandment also means obedience to your parents. I notice you are over 18 so I guess you are free from the duty of obedience but you will always have the duty of respect towards your parents.
IMHO you can’t love God and sin at the same time. Love and sin are both acts of the will. You can either will to do what God wants or will against Him.
It is sin for an unemancipated child to disobey his parents, unless what the parents say goes against God’s law.
It is sin to break man’s law (you are right, God has given us authorities, it is His judgment) unless that law goes against God’s law.
Hope this helps.
