The apostle John wrote not only the gospel record but also three letters in each of which he urged the disciples to keep the commandments, especially to love one another. His gospel emphasised that Jesus is the Son of God and these letters speak particularly of the disciples as the sons of God. Like all the other apostles, he warned the disciples against false prophets and urged them to maintain the purity of the truth.
