How Is It Possible To Not Sin?

In this episode Dr. Betters answers the question, "I had a question regarding sin itself. I know In scriptures it tells us “We are all sinners and fall short of the glory of God”. It also says that “if we say we have no sin, then we are only fooling ourselves and not living the truth”. So my question is, why then does scripture say “go and sin no more” as Jesus said to the woman if we are always going to sin? Does Jesus mean practicing sin? Thanks! And love your videos."
