In his letters John recalls us to the things which matter most with his message to live in God's love. David Jackman demonstrates that the force of John's searching analysis can be felt in our lives today. 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.
