The law of God is not to be followed blindly because it is designed to bring us freedom. However, this is not always obvious to us, and thus we need to study God's Law, particularly when we disagree with some part of it and feel like setting it aside. Every part is made for our flourishing.
Based on Psalm 19:8-11:
the precepts of the Lord are right,
rejoicing the heart;
the commandment of the Lord is clear,
enlightening the eyes;
the fear of the Lord is pure,
enduring for ever;
the ordinances of the Lord are true
and righteous altogether.
More to be desired are they than gold,
even much fine gold;
sweeter also than honey,
and drippings of the honeycomb.
Moreover by them is your servant warned;
in keeping them there is great reward.
