This attempt to outline the Scripture teaching on this character will be undertaken under certain general conditions: First--The authority of the Scriptures of both the Old and the New Testaments will be accepted without question. Second--Evidence will be drawn from the Word of God alone, since no final light can be found on this subject other than it has pleased God to reveal in the Bible. Third--There will be no discussion as to the actual existence of Satan; this being both assumed and taught from Genesis to Revelation. These pages are prepared especially for believers; knowing that this body of truth will be wholly unnoticed or rejected by the Satan-blinded world (2 Cor. 4:4). There has also been a deep sense of the seriousness of the undertaking: both because Satan, by his present direct power, would, if possible, hinder any larger understanding of his projects and purposes; and because so great a warning has fallen from the lips of Christ against the sin of ascribing to Satan the things which are really of God (Matt. 12:22-32). The work has, therefore, been undertaken with some degree of reliance upon the keeping and guiding power of the Spirit of God, and is presented with the prayer that believers may have a clearer understanding of this important body of truth and be able to say with Paul, "We are not ignorant of his devices." It is also desired that some clearer vision of this mighty foe may be had which will cause the child of God to realize the overwhelming power of his adversary and be constrained to "be strong in the Lord and in the power of his might;" that greater victory may be had in the realization of the whole will of God. Chapter I. The Career of Satan This chapter is a brief outline of the past, present and future of Satan, which is taken up at this point both that the following chapters may be more easily studied and because of the fact that those passages which deal most directly with his earliest condition are closely interwoven with predictions of his future and final defeat.
