God’s Law is the only thing that can morally bind his creatures, as there is fundamentally only one Lawgiver (Isa. 33:22; James 4:12).
Hence, all human laws and commands, including from those who hold public offices of God, only oblige as far those commands reflect God’s Law inherent in the situation itself, and to that degree.
Yet persons and authorities often expect to be obeyed simply because they have so willed it. When you are presented with this unpleasant situation, here is a page of reformed resources that will help you understand this error (and the truth it opposes) better, and it will confirm you in walking in this life as a servant of God, and not of men.
Likewise, to give anyone besides God our implicit faith and obedience (if they demand of us to believe or obey anything wherein a sufficient moral reason is not perceived or given to our conscience) is against the 2nd and 7th Commandments:
It is written: “What doth the Lord thy God require of thee, but to… love Him and to serve the Lord thy God…” (Dt. 10:12) But to serve the will of man apart from being able to serve God’s will in the matter is idolatry, to enthrone service to the creature above God. It is also to perversely give up our soul’s most precious inner-chamber, reserved for God alone, to be used by men.
