1 John

The apostles declare their personal witness to the life of Jesus Christ and their fellowship with the Father and the Son, which they share with others to bring full joy. True fellowship with God requires walking in the light and acknowledging sin, which is forgiven and cleansed by the blood of Jesus Christ. The writer emphasizes the importance of not sinning, but if one does, Jesus Christ is the advocate with the Father, and true knowledge of God is demonstrated by keeping His word. The writer warns against loving the world and its desires, and against false teachers who deny Jesus Christ, while encouraging believers to abide in Christ and love one another, demonstrating the love of God by laying down one's life for others.
