A. W. Pink on Satan from Wisdom-of-the-Wise.com

"Satan is the arch-counterfeiter. As we have seen, the Devil is now busy at work in the same field in which the Lord sowed the good seed. He is seeking to prevent the growth of the wheat by another plant, the tares, which closely resembles the wheat in appearance. In a word, by a process of imitation he is aiming to neutralize the Word of Christ. Therefore, as Christ has a Gospel, Satan has a gospel too; the latter being a clever counterfeit of the former. So closely does the gospel of Satan resemble that which it parades, multitudes of the unsaved are deceived by it."
