Uses a 'cyclical' style, repeatedly coming back to the themes of Truth and Love.

Jesus is our Advocate with the Father (2:1) and the Propitiation for our sins.

1 John 1 - The Word of Life

We have seen and proclaim to you the Word of life. God is light. If we walk in the light, the blood of Jesus cleanses us from all sin.

1 John 2 - Christ Our Advocate

We know Christ if we keep his commands. Whoever loves his brother lives in the light. Do not love the world. Children, abide in him.

1 John 3 - Children of God

We are God's children. Those born of God do not sin. We should love one another. We know love because he laid down his life for us.

1 John 4 - Test the Spirits

Any spirit that confesses Christ is of God. God is love. He sent his Son as a sacrifice for sins. If we live in love, God lives in us.

1 John 5 - Jesus is God

Anyone born of God overcomes the world. The Spirit, water and blood all testify. God gave us eternal life in his Son. Keep from idols.
