'Obey' in the Bible

but to those who are selfishly ambitious and do not obey the truth, but obey unrighteousness, wrath and indignation.

Therefore do not let sin reign in your mortal body so that you obey its lusts,

Do you not know that when you present yourselves to someone as slaves for obedience, you are slaves of the one whom you obey, either of sin resulting in death, or of obedience resulting in righteousness?
