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

"True Christianity" by Johann Arndt is a theological exploration of what it means to live as a genuine Christian in the early 17th century. The book examines the critical ideas of heartfelt repentance, authentic faith, and a sacred lifestyle as hallmarks of a true believer, highlighting the need for inner spiritual change and righteous behavior, arguing that faith should be demonstrated through actions and dedication rather than just following religious customs; in essence, it begins with Arndt's worries about the widespread impiety he sees in those who call themselves Christians, stressing that real Christianity arises from an energetic faith that results in a changed existence, calling on believers to embody Christ in their everyday lives, with Arndt stressing that understanding God's teachings requires obedience and a real fight against sin, creating a setting for thoughtful self-examination of faith and the traits of a devoted Christian.
