The Apostle Paul declares that "By faith ye are saved." Some people cannot exercise the quality of faith. The Apostle also declares that faith cometh by hearing, and hearing by the Word of God, which means in order to have faith one must study the Word of God and believe it. The Apostle Paul answers this question when he declares that the God of this world (Satan), manifested in this present evil order of things, has blinded the minds of those who do not believe (`2 Cor. 4:4`). The great Adversary, Satan, is the author of so many false doctrines that many good, honest people have become greatly confused by them. One system has taught one doctrine, another class, equally honest, another doctrine, until we have in the world more than three hundred different denominations, all having some truth mixed with much error. Many honest people have been unable to separate the truth from the error, and accept only the truth and reject the error, hence the confusion and refusal to have anything to do with either. If all were to follow the admonition of the Apostle, "Study to show yourself approved unto God," and not follow man-made theories, there would be less confusion and more who would readily accept the Scriptural teachings.
