How can we know that we possess eternal life? The apostle John answered that question in the three epistles that bear his name. He wrote that we must firstly believe that Jesus is the Son of God and that Christ came in the flesh. Secondly, we are to obey God’s commandments. Thirdly, we must love others.

In this illuminating and engaging commentary on John’s letters, pastor-scholar Douglas Sean O’Donnell illustrates and applies these three essential tests that judge whether we possess eternal life or not. Grow in your knowledge of Christ, our Savior. Learn how to live in the light. Grab hold of the gospel-transformed life!
