Take a compass,and position it so that the needle points north.
Now place a magnet at the side of the compass.What happens? The needle no longer gives an accurate reading.Instead,it is turned towards the magnet.
Your conscience is like that compass.If properly trained,it will point north and help you to make wise decisions.
But harmful association,like a magnet,exerts a pull that can distort your moral Judgment.
Try to avoid people and situation that may throw your moral sense off course!
