John warns believers in Christ to guard their hearts and lives against loving the world. Love for the world and love for God run contrary; you cannot love both at the same time. John provides specific examples of love for the world that is sinful. Furthermore, he explains that this world and its desires are dying. A new era of the Kingdom of God has dawned with the incarnation and resurrection of Christ. This world is passing away and will not last. But the ones who love God and do His will, will live forever.
