George Matheson, a Scottish minister, describes the aspects of the human spirit, identifying some ninety-five qualities and virtues expressed by the very essence of man.

Designed as a daily reference for Christians, each of the chapters in this book explain a defining quality of the human spirit. The human affinity for the divine, the steps and character of spiritual attainment, and the enormity of the spirit's power and capacity, are but a few topics at hand. Matheson variously places each chapter in a Biblical or a personal context, quoting relevant passages of scripture as an example or starting point for each chapter.

A gifted hymnwriter and preacher, Matheson spent his life in service to God. Though he gradually became blind during childhood and adolescence, he demonstrated a gifted mind in studies of logic and philosophy. His dream to become a minister was fulfilled, and his ministry commenced in the coastal town of Innellan, where his preaching was well-received.
