Today the Asian church ministers in a multi-religious and often multi-cultural environment and faces serious challenges. Thankfully, we have a resource that offers guidance and encouragement: the ancient documents known as 1, 2 and 3 John. In this commentary, Dr. Gilbert Soo Hoo provides careful textual analysis alongside contextual relevance in the hope that the reader will hear God's voice, encouraging them to become disciples that live in fellowship with the Father and the Son and with one another. The fundamental Christological truths presented serve as a template to help evaluate various teachings and to discern what is true and what is false, which is critical for believers living and serving in multi-religious Asia.
