Dr. Johnson said: "Conscience is the sentinel of virtue." The wise captain never lets his men sleep on the field without posting one or more sentinels. The young man going out into the world is going on to the battlefield of his life, and to be caught napping is to fall into the enemy's hands. He needs all his forces, and, above all, the sentinel, Conscience, to keep guard when the enemy is lying in ambush, and danger seems far away. St. Paul tells us that if we wish to war a good warfare we must have two things, "Faith, and a good Conscience." "No whip cuts so sharply as the lash of Conscience." "The voice of Conscience is so delicate that it is easy to stifle it; but it is also so clear that it is impossible to mistake it."
