Written by John the Elder to house church believers, 1 John, 2 John, 3 John echo the gospel of John. They emphasize that God is light and love and every true believer will demonstrate God's light and love. Each book also addresses deceivers, teachers who no longer acknowledge that Jesus is the Messiah or Son of God but spread fear and division among believers.
All legitimate teachers will share the truth about Jesus and the cross, love others sacrificially and spread love and light rather than fear. He also reminds believers to welcome true missionaries who teach the message of the cross and love others. They should not welcome deceivers or make idols of anything that exalts itself in God's place.
1 John, 2 John, 3 John addresses deceivers who no longer acknowledge Jesus as Messiah or God's Son and stir up hostility among faithful believers.
God is Light
God and Jesus are light. To participate in life with God, believers must keep Jesus' commands to love each other and not love the world.
God is Love
God's children should follow Jesus' example to love others. Believers gain victory over the world when they receive God's love and then love others sacrificially.
Teachers who deny Jesus and His work on the cross or command to love others is a deceiver and should be unwelcome by the church.
Giaus, a house church member, is encouraged to welcome legitimate traveling missionaries who will arrive soon rather than reject anyone associated with John the Elder.
