1 John

The apostle testifies to the reality of Jesus Christ, the Word of Life, and emphasizes the importance of walking in the light to have fellowship with God and one another. Those who claim to have fellowship with God must acknowledge their sin and be cleansed by the blood of Jesus Christ. The apostle encourages believers not to sin, but if they do, Jesus Christ is their advocate and propitiation for their sins. Believers must keep God's commandments, love one another, and not love the world and its desires. The apostle also warns against antichrists who deny Jesus is the Christ and encourages believers to abide in the Son and the Father.
