This book is a must read for three reasons. First, no other book can compare. It is the most comprehensive work affirming Eternal Security in the history of Christendom! Second, Dr. Olson uses his experience gained as a Lutheran pastor and evangelist to compare the arguments for and against eternal security side by side. Third, critical aspects of theology underlying Eternal Security that are customarily overlooked or avoided are integrated into each passage as Theological tidbits.Dr. Olson presents the key features of each passage in a clear, concise, easy-to-understand manner. Eternal Security in the brilliant light of God's word and Luther's penetrating dictum: "justification is the chief article of theology by which the church or asn individual stands or falls." God's gracious promise of eternal life is discussed in light of the critical understanding of justification and sanctification. Eternal Security is the authentification of sound doctrine. It is God's grand guarantee of faithfulness providing courage to the martyr, hope to the faithful, and assurance for less than perfect saints. OSAS is the proof that the door into God's Kingdom only works one way. It is the pest hound of heaven for the skeptic and the license of peace for the saints. It is the truth that pilgrims find at the end of the road.
