The goal of this commentary is to bring the theological themes of the gospel of John into focus and apply them to the lives of present day disciples, that they may be sanctified in the Word of Jesus. Unlike other commentaries, this one was written originally in Spanish and interpreted in a Hispanic context. It includes pertinent information about the historical, geographical, anthropological, sociological, and literary framework in which the book was written. It also offers references to rabbinic and apocryphal literature, helping the student to better understand the background of the first century world. \"Dr. Blank prepared this commentary as a tool for pastors and leaders of the Hispanic church, both in the United States and in Latin America. It is useful for the preparation of sermons, Bible studies, and for Christian education. This wide variety of uses does not take anything away from its academic depth. For instance, the Greek terms are analyzed with care, and a variety of scholarly opinions on the texts are offered. The author\'s experience as a missionary in Latin America adds a unique perspective, creating a dynamic mix of historical, exegetical, and practical theologies.\"
