Summary: In this part of his letter John says he writes so that we may not sin, but if anyone does sin then the atoning sacrifice of Jesus Christ has dealt with our sin. He expounds on how knowing God means we will keep his commandments and love our brother. He talks about how the antichrists being revealed are because it is the final hour, but we have an anointing from the Holy One so know the truth. Read from the World English Bible.
