“The conscience is an organ of extraordinary delicacy, representing the deepest feelings of the human spirit. Like a sensitive recording instrument, influenced by every change of weather, it is liable to be damaged by any shock. When we thoughtlessly leave the doors of our inner life open to the ever-changing atmosphere of the times, the conscience is in danger of being thrown off balance.” Eberhard Arnold. 

Someone made the point that conscience, to function properly, must be set to the ‘magnetic north’ of Scripture. Such fine-tuning is an on-going process.
