Malachi 1:6
A son honoureth his father, and a servant his master: if then I be a father, where is mine honour? and if I be a master, where is my fear? saith the LORD of hosts unto you, O priests, that despise my name. And ye say, Wherein have we despised thy name?
As Father and Master, God claims from his people the honor a son gives a father and the reverent fear a servant gives a master, and he rebukes the priests and his professed people for withholding it and thereby despising his name. The priests despised his name by bringing polluted offerings of blind, lame, sick, torn, cheap, and self-serving animals and by treating his table and worship as contemptible, contrary to the requirement to present the best, without defect. Offering God such defective things and doing his work only for pay without willing reverence is evil, would not be accepted by an earthly ruler, and God has no pleasure in it and will not accept it from the hand that brings it. The reproof teaches that worship offered to God must not be careless or defective.
Putting common things in place of holy things dishonors God, so using the seventh day he reserved, sanctified, and blessed for himself as a common working day and giving him in its place a day he has not blessed is a great sin that robs God. Even without worshiping idols or graven images, people despise God when they idolize one another, praising, petting, and exalting poor, frail, erring men instead of giving him the honor that belongs to him. That despising of God is shown when people assimilate to the world, lack love and forbearance toward brethren, listen to smooth preaching of peace, and rest at ease in Zion as if the church is flourishing.
The principle also applies today to presenting the body as a living sacrifice, which requires habits that preserve physical, mental, and moral health rather than offering a life impaired by harmful habits.
