Christianity differs from other religions in one key aspect - Jesus Christ. If you remove Jesus Christ, Christianity is void. All other religions can still stand without their founders.
The main themes of 1 John are about Jesus Christ the Eternal Life, the Light and the Love. We who has fellowship with Jesus must walk in the light and in love. By walking in the light, we stay away from sin. Sin is revealed by the Light. Sin breaks fellowship. Sin and its effects, however, are removed by our confession. It is also about exposing the evil and staying away from the lusts of the world. Fellowship with Christ is also about love in action. Love is proactive - it acts first. Love is about obedience. Love is without fear. Our loving deeds assure us that we are of God who is Love.
I find John writing to be a bit repetitive. He tends to say the same thing in different ways. It shows that our language are too restrictive to explain the greatness of Jesus and His love.
The main title for the 5 chapters are :
- Jesus, True God Came
- The Growth Stages
- Believers Love like Their Father & Sin not
- Discernment & True Love
- Our Identity & Authority
