True Christianity A Treatise on Sincere Repentence, True Faith, the Holy Walk of the True Christian, Etc.

"True Christianity" by Johann Arndt is a treatise written in the early 17th century. This theological work seeks to elucidate the concepts of sincere repentance, genuine faith, and the holy life of a true Christian. With a focus on inner spiritual transformation rather than mere external adherence to rituals, Arndt emphasizes the necessity for believers to embody their faith through righteous conduct and heartfelt devotion. At the start of the treatise, Arndt introduces his motivations for writing, expressing concern over the prevalent ungodliness he observed among self-identified Christians. He asserts that true Christianity is rooted in a living and active faith that leads to repentance and a transformed life, in which believers must strive to reflect Christ in their daily actions. Arndt emphasizes that knowledge of God’s word must be accompanied by obedience and a genuine struggle against sin, setting the stage for deep personal reflection on the nature of faith and the qualities of a faithful Christian life.
