The letters of John are some of the most simple yet profound texts in the New Testament. The Apostle John wrote three epistles at the close of the first century to counteract the heresy of Gnosticism and to focus on what it meant to know God by walking in His light. He contrasted the Christian life in stark opposites--light and darkness, love and hatred, truth and lies, life and death. In Living in the Light, Derrick McCarson reveals the heart of John's message: salvation is not found in hidden, secret knowledge, but in the fellowship of Christ. Moreover, the evidence of salvation is seen by loving others, abiding in the truth and obedience to God's commands. Living in the Light is a verse-by-verse commentary on the epistles of John. This volume is ideal for believers who are looking to go deeper in their discipleship with Christ. With an emphasis on practical application and precise exposition, this book will enhance the reader's personal Bible study.
