_Tit. 1. Advice against Murder._ Though murder be a sin which human nature and interest do so powerfully rise up against, that one would think besides the laws of nature, and the fear of temporal punishment, there should need no other argument against it; and though it be a sin which is not frequently committed, except by soldiers; yet because man's corrupted heart is liable to it, and because one sin of such a heinous nature may be more mischievous than many small infirmities, I shall not wholly pass by this sin, which falls in order here before me. I shall give men no other advice against it, than only to open to them, 1. The causes; 2. The greatness; and 3. The consequents of the sin. I. The causes of murder, are either the nearest, or the more radical and remote. The opening of the nearest sort of causes, will be but to tell you, how many ways of murdering the world is used to! And when you know the cause the contrary to it is the prevention. Avoid these causes, and you avoid the sin. 1. The greatest cause of the cruellest murders is unlawful wars. All that a man killeth in an unlawful war, he murdereth; and all that the army killeth, he that setteth them at work by command or counsel, is guilty of himself. And therefore, how dreadful a thing is an unrighteous war! And how much have men need to look about them, and try every other lawful way, and suffer long, before they venture upon war! It is the skill and glory of a soldier, when he can kill more than other men. He studieth it; he maketh it the matter of his greatest care, and valour, and endeavour; he goeth through very great difficulties to accomplish it; this is not like a sudden or involuntary act. Thieves and robbers kill single persons; but soldiers murder thousands at a time: and because there is none at present to judge them for it, they wash their hands as if they were innocent, and sleep as quietly as if the avenger of blood would never come. Oh what devils are those counsellors and incendiaries to princes and states, who stir them up to unlawful wars!
