They were also advised that they were to uphold the constitutional law of the land, for it has been established by the will of God, therefore we are justified “in befriending that law which is the constitutional law of the land; and as pertaining to law of man, whatsoever is more or less than this cometh of evil” [D&C 98:6–7].

When we abide in the law which the Lord has approved, then we are free. It was his mighty hand which directed the founders of the government of the United States and gave this nation the constitution in the beginning. . . . The constitutional law was given by inspiration for the purpose of protecting the rights of the citizens of the country. The Lord delights in freedom.
