"Systematic Theology (Volume 1 of 3)" by Augustus Hopkins Strong is a theological reference work written in the early 20th century. This comprehensive publication serves as a guide for theological students, addressing fundamental doctrines of Christianity. The first volume specifically focuses on the Doctrine of God, exploring critical aspects such as the existence and nature of God, the Trinity, and the relationship between God and humanity. The opening of this work includes a detailed preface, in which the author expresses his motivations for revising and expanding his original publication from 1886. He discusses the importance of theology in understanding the divine and emphasizes the doctrinal foundations of Christianity as essential for individual character development. The text defines theology as both the science of God and the study of the relationships between God and the universe, establishing that the existence of God, humanity's capacity to know God, and divine revelation are foundational topics that will be explored in detail throughout the volume.
