Over the course of John’s Letters, he has worked through three primary themes: (1) Know God, (2) Believe the Gospel, and (3) Love one another. (Summary of 1, 2 and 3 John)

In 3 John, the Apostle John contrasts living for Christ versus living for self. Everyone is someone’s disciple; what kind of master do you serve? (Exposition of 3 John)

In 2 John, the apostle John gives us a case study of the themes of 1 John. Specifically, John shows how love and truth fit together in the Christian life. (Exposition of 2 John)

In the closing section of his First Letter, the Apostle John insists that Jesus Christ is God and eternal life—and that we should therefore keep ourselves from idols. (Exposition of 1 John 5:18–21)

Building on what he wrote about faith in the previous passage, the Apostle John now shifts his attention to prayer—especially prayer for the prodigal brother. (Exposition of 1 John 5:13–17)

What is faith? Where does faith come from? How do we get faith? What does faith do? Toward the end of his First Letter, the Apostle John answers these questions. (Exposition of 1 John 5:1–12)
