The heart of man is the seat of sin, and where he is defiled he must be sanctified; and where sin lives, there it must die: it must be crucified. Custom in evil hath made it natural to men to do evil; and as the soul rules the body, so the corrupt nature sways the whole man: but still, it is all from within. IV. Experience teaches every son and daughter of Adam to assent to this; for the enemy's temptations are ever directed to the mind, which is within: if they take not, the soul sins not; if they are embraced, lust is presently conceived, that is, inordinate desires; lust conceived, brings forth sin; and sin finished, that is, acted, brings forth death. (James, v. 15.) Here is both the cause and the effect, the very genealogy of sin, its rise and end. In all this, the heart of evil man is the devil's mint, his work-house, the place of his residence, where he exercises his power and art. And therefore the redemption of the soul is aptly called the destruction of the works of the devil, and bringing in of everlasting righteousness. (1 John, iii. 8.; Dan. ix. 24.) When the Jews would have defamed Christ's miracle of casting out devils, by a blasphemous imputation of it to the power of Beelzebub, he says that "no man can enter into a strong man's house, and spoil his goods, till he first bind the strong man." (Matt. xii. 29.) Which, as it shows the contrariety that was between Beelzebub and the power by which he dispossessed him, so it teaches us to know that the souls of the wicked are the devil's house, and that his goods, his evil works, can never be destroyed till first he that wrought them, and keeps the house, be bound. All which makes it easy to know where the cross must be taken up, by which alone the strong man must be bound, his goods spoiled, and his temptations resisted, that is, within, in the heart of man. V. But in the next place, how and in what manner is the cross to be daily borne?
