on any other point, and the denial of a personal Devil involves the trustworthiness of the Lord Jesus as a Teacher and a Saviour at every point. So we see that the question of the existence of the Devil is fundamental and of vital importance. II. THE NATURE OF THE DEVIL Having settled it that there is a Devil, we now face the question as to the nature of the Devil. 1. First of all, the Bible teaches us that the _Devil is a person_. This comes out in our second text, 1 John 3:8: +"The devil sinneth."+ Only a person can sin. When we say that the Devil is a person we do not mean that necessarily he has a body, certainly not such a body as he is pictured as having in various paintings and engravings that are supposed to represent the Devil. A person is any being who knows and feels and wills. When we say that the Devil is a person we mean that he is a being who has intelligence, feeling and will, that he is not a mere principle of evil. The personality of the Devil is taught over and over again in the Bible. Just a few illustrations in addition to our texts. Turn again to Matt. 13:19: +"When any one heareth the word of God, and understandeth it not, then cometh the evil one, and snatcheth away that which hath been sown in his heart."+ The representation of this passage is the representation of a person. He is called "The Evil One," not merely "evil," but "The Evil One," which of course is the representation of a person. If evil is only impersonal, or if it only works through human beings, these words of our Lord Jesus would be without meaning. The personality of the Devil comes out again very clearly and very forcibly in Eph. 6:10-12: +"Finally, brethren, be strong in the Lord and the strength of his might. (11) Put on the whole armour of God, that ye may be able to stand against the wiles of the devil. (12) For our wrestling is not against flesh and blood, but against the principalities, against the powers, against the world rulers of this darkness, against the spiritual hosts of wickedness in the heavenly places."+ Here Paul distinctly tells us that the great reason why we need to be strong in the Lord and in the strength of His might and why we need to put on the whole armour of God, is because there is a being of great cunning, subtlety and power, a person named "The Devil," and that this being has under him a multitude of other personalities of such dignity and power as to be called by the titles: "principalities," "powers," "world rulers," "spiritual hosts of wickedness." Beyond a question our Lord Jesus, and the Apostle Peter and the Apostle John and the Apostle Paul believed in and taught the existence of a personal Devil. If there is not a personal Devil we may as well give up our Bible, for in that case it is a book that is full of folly and of fraud. If there is not a personal Devil we must give up our belief in the inspired authority of the Apostle Paul, the Apostle Peter, the Apostle John, and we must
