The apostle John is often called “the apostle of love” because his writings are full of the love of God. However, John, like many of us has a less than ideal past. John was called the son of thunder until the love of Jesus Christ changed him forever. In 2 John, the beloved disciple reminds us to rejoice in the truth of the Gospel that Jesus came to save sinners. Having been transformed by this truth, John tells us three things; (1) we can rejoice in the law because Christ has born the judgment for our failings, (2) we can rejoice in the church because we share an inheritance based on Christ’s work for us, (3) but we must guard our hearts because those we allow to influence our lives can lead us away from the truth of the Gospel.
