(and the life was revealed, and we have seen, and testify, and declare to you the life, the eternal life, which was with the Father, and was revealed to us);

 So John condemns the man who claims that he is so far advanced in knowledge and in the spiritual life that sin for him has ceased to matter; he condemns the man who evades the responsibility for his sin or who holds that sin has no effect upon him; he condemns the man who has never even realized that he is a sinner. The essence of the Christian life is first to realize our sin; and then to go to God for that forgiveness which can wipe out the past and for that cleansing which can make the future new.
