The true light is already shining (1 Jn 2:8)

1 John is a treatise that was written by an unknown author in language similar to that used in John's gospel. The Christian community had suffered a schism (2:19). The author seeks to restore fellowship by reminding readers that all have sinned. Those who say they are in the light but continue to hate their brothers and sisters in the faith remain in darkness. The author warns against those who deny that Jesus Christ came in the flesh (4:1-3) repeating that those who love God must love other Christians (4:21).

1 John 1:1-10 - The word of life
1 John 4:16-21 - Perfect love
