In a climate of disunity and doctrinal deviation, the apostle John called his first readers to live in the love and truth of God. David Jackman has no doubt that John's letters are a vital, powerful word from the Lord to the church today around the world.So often we take extreme positions, leading to a fragmentation of both churches and individuals.This book will help us to respond afresh to the apostle's call to love one another and live in the light.
