*** w88 4/1 pp. 30-31 Is Obedience Always Proper? ***
Jehovah does not expect us to show blind credulity. He does not want from us the kind of obedience that a trainer gets from a beast with a bridle or a whip. That is why he told David: “Do not make yourselves like a horse or mule without understanding, whose spiritedness is to be curbed even by bridle or halter.” (Psalm 32:9) Rather, Jehovah has endowed us with thinking ability and discernment so that, based on understanding, we can choose to obey him.
