The Character and Intention of the Devil
There is a devil! We have a mighty invisible enemy always near us–one who never slumbers and never sleeps–one who is about our path and about our bed, and spies out all our ways, and will never leave us until we die. He is a murderer! His great aim and object is, to ruin us forever and kill our souls. To destroy, to rob us of eternal life, to bring us down to the second death in hell, are the things for which he is unceasingly working. He is ever going about, seeking whom he may devour. He is a liar! He is continually trying to deceive us by false representations, just as he deceived Eve at the beginning. He is always telling us that good is evil and evil good–truth is falsehood and falsehood truth–the broad way good and the narrow way bad. Millions are led captive by his deceit, and follow him, both rich and poor, both high and low, both learned and unlearned. Lies are his chosen weapons. By lies he slays many.
